THE TECHNICAL COORDINATOR
Jeff Kopcak – TC
k8jtk@arrl.net

Hey gang,

As Technical Coordinator for the Ohio Section, I oversee the section’s Technical Specialists. We are here to promote technical advances and the experimentation side of the hobby by encouraging amateurs in the section to share their technical achievements in QST, at club meetings, in club newsletters, and at hamfests and conventions. We are available to assist program committees in finding or providing suitable programs for local club meetings, ARRL hamfests, and conventions within the section. When called upon, serve as advisors for RFI issues and work with ARRL officials and other appointees providing technical advice.

Technical Specialists are a cadre of qualified and competent individuals here for the “advancement of the radio art,” a profound obligation incurred under the rules of the FCC. TS’s support myself and the section in two main areas of responsibility: Radio Frequency Interference (RFI) and technical information. They can specialize in one or more areas or be generalists with knowledge in many areas. Responsibilities range from serving as consultants or advisors to local hams or speaking at local club meetings on popular topics. In the Ohio Section, there are 12 qualified specialists.

RFI and EMI (electromagnetic interference) includes harmful interference that seriously degrades, obstructs, or repeatedly interrupts a radio communication service such as ham radio or public service agencies. RFI sources range from bad power insulators, industrial control systems, nearby or poorly made transmitters, household appliances, personal devices like computers, monitors, printers, game consoles – to grow lights, failing or poorly made transformers, and devices hams brag about getting cheap from China. Technical Specialists can offer advice to help track down interference or locate bozo stations when called upon. Technical information is wide-ranging, everything from antennas to Zumspots.

How can we help? The knowledge and abilities of YOUR Technical Specialists are really quite impressive:

Amplifiers
Antennas (fixed, portable, emergency operation)
Antenna systems such as towers, guying, coax/feedlines, and baluns
Boat anchors (tube technology)
Computer systems – Windows, Linux, Raspberry Pi
Digital voice and data modes – including D-STAR, DMR, Fusion, NXDN, P25, APRS, IGates, packet, TNCs, MT63, FT8/4, Olivia, PSK, etc.
Direction finding
Electronics and circuits, including teachers whom have taught electronics classes
Former repair technicians
Home brew
Internet linking (Voice over IP, aka VoIP) – Echolink, AllStar/HamVoIP, DVSwitch, PBX/Asterisk
Mobile installations – HF, VHF/UHF, antennas
Narrow Band Emergency Messaging System (NBEMS) – Fldigi and Flmsg
Networking – AMPRNet, routers, port forwarding, ISPs, firewalls, mesh, microwave
Power supplies
Propagation
Repeaters, controllers, and high-profile systems
RFI caused by power lines and consumer appliances
RF safety
SHARES stations (SHAred RESources – Department of Homeland Security HF radio program)
Software Defined Radios (SDR)
Tower safety
Professional certifications such as Motorola Certified Technicians, Master Electrician, Certified Journeyman Electronics Technician, General Radiotelephone Operator License (GROL), ETA certifications, Society of Broadcast Engineers (SBE) certifications and affiliations, and Marine Radio Operator permit holders.

This impressive list of qualifications are available resources to all in the Ohio Section. Looking for guidance in one of these areas? Need a program for your club meeting? How about a technical talk or forum at a hamfest? Assistance or direction on a project? My contact info is near my picture and on the arrl-ohio.org website. I’ll assist getting you in touch with an appropriate Technical Specialist.

Hamvetion Recap

Original 1964 Collins Communication Van at Hamvention

Another Hamvention has come and gone. This was emotional because this was the first since my dad passed, N8ETP. Hamvention was something we did together. He didn’t go last year because (we didn’t know it at the time) he was suffering from post-operation complications. He was looking out from above because I had no shortage of company on this trip. I checked into the hotel, then went to dinner. Immediately met a father and son on their first trip to Hamvention. We talked about the show, past shows, what to expect, and some pro tips. Ironically, the dad was released from the hospital a week prior after recovering from an infection. If they’re reading, I apologize I don’t remember your calls – send me a message and I’ll add them later.

Figuring the rain would keep attendees away Friday morning, traffic was worse than anticipated. Busses were stuck in with those trying to get into on-site parking, causing delays and lines at the high school. It took over an hour from the high school until I got into the fairgrounds. Broke out the poncho for the first time in a number of years.

After being admitted, checked in with the ARRL Ohio Section/Great Lakes Division table to say howdy to our leadership and swap stories. Shortly after leaving the booth, ran into George – W5JDX and Mike – VE3MIC from AmateurLogic.TV and spent the rest of the day hanging out with those guys. Due to rain, George didn’t do any recording until after we grabbed some lunch. Hilarity insured behind the camera as well as in front.

I left about 4pm to get ready for dinner. At dinner, I ran into George again. We were chatting and before we knew it, realized it was 8pm. We had intended on going to the D-STAR evening gathering but didn’t make it since we were having a big time.

Saturday, ran into Mike – this time in the flea market – and we walked a good portion of it in the morning. Mike and cousin Jerry were going to head back home around noon. I walked the rest of the flea market because that was something dad liked to do too. Before leaving, talked with some inside vendors I wanted to speak to.

Shopping list was sparse this year. Only thing I was really looking out for was a place that built ham shacks/outdoor buildings. The camper converted into my existing hamshack really needs to be replaced. I didn’t see any builders there. Rest of the shopping list was “nice to haves” – radio with a TNC for APRS or Winlink. Maybe other APRS gear. Couple Motorola pieces of equipment I’ve been looking for. Been wanting to get a D-STAR radio with the latest features. I took advantage of a show special at DX Engineering and picked up an ICOM ID-52, mainly because the restrictions (by ICOM) were lifted on the show specials.

A ham in the area, whom I’ve gotten to know, was looking to unload some of his gear. I picked up a used ICOM IC-746Pro and Micro Keyer. Fortunately, I was able to try out the radio before I bought it. Doing some research online found out the most common problems with the 746 are the display backlight goes flaky, eventually crapps out, and a dead transmitter. Both were non-issues.

This ham did say the tuning knob might be loose. It didn’t seem much different than my IC-7000. Upon using it at home, there might be an issue with the knob because it does repeat the same frequency numbers over and over again on occasion. I’ll look into tightening or cleaning the knob/encoder to see if that resolves it. It’s not a big deal because most of my operation is digital and I use remote control through a CI-V cable.

Otherwise, it’s been working fine on Winlink. There are a couple differences I like in my 7000 over the 746. Main one being it keeps switching back to USB from D-USB for digital operation. Functionally, it’s working as expected.

A stop at Micro Center in Columbus on the trip back home is required for some post-Hamvention spending. The Columbus location is a bigger store than my closest location on the east side of Cleveland (Mayfield Heights), which means they have more stuff out on display. I needed some larger capacity USB Flash Drives and they had a Lenovo ThinkPad on sale. I’d been having trouble with my existing laptop failing to charge the battery. I found out the Columbus store is a larger location because it is the flagship store for Micro Center as their headquarters are about 15 minutes away. That store will have items not (yet) available at other locations as a test to see if an item sells out.

The same general themes kept popping up before the show and at the show from other attendees: ‘this maybe [my] last one’ and ‘show specials can be found online.’ With the economy in the crapper and inflation in its current state, it’s getting even more expensive to attend Hamvention. $500 and up for a single room in the area for the weekend. With other local events, such as grade school sporting tournaments and antique flea markets, hotel rates are higher due to demand. There were a couple issues at my hotel too. While the staff tried to make it right offering bonus points, the issues still shouldn’t have happened when you’re paying that much for a room. An inconvenience for what was supposed to be an otherwise enjoyable time.

Hamvention show specials, for the most part, can be found online too. Not all distributors bring a lot of gear (inventory) to sell – except for maybe the most popular radios and models. Heil Sound is one vendor most people I know reference because we were involved with Ham Nation. Back at Hara Arena, they had an entire side of Audio Alley with equipment and inventory for sale. Heil Sound had a 6-foot table this year showcasing headset and some microphone offerings. They, like many others, are relying on distributors for show specials and handling of inventory – which goes back to the show specials are also found online. MFJ wasn’t there because they ceased production as the show was getting underway. I heard in the flea market: ‘sellers are looking for top dollar and buyers are looking for the cheapest deals.’ Things weren’t flying out of the flea market either.

Despite that, according to the Hamvention website, this year’s event was record-setting attendance at 35,877. I will always be of the belief “if you’ve never been to Hamvention, you need to go at least once in your life.” It’s more of a social and nightlife gathering, with vendors putting new gear ‘under glass’ at the show.

ARRL Network Incident

Not to bury the lead but I figure I would touch on the announcement posted on the ARRL website regarding the “serious incident involving access to our network and headquarters-based systems.” This incident was big enough news to make an online Cybersecurity trade publication, SecurityWeek. I don’t know anything more than the information made available in the league’s post but I suspect the last paragraph in the SecurityWeek article is the reason.

From the Information Security side, in this day and age, where everyone wants things to be convenient – conveniently accessible resources, conveniently ways to order things online, convenient ways to make membership changes, convenient apps to use – it’s not a matter of “if” something will be compromised, but “when” will something be compromised. The “when” for the ARRL happened to be right before Hamvention.

As noted in the ARRL post, people are asking if personal information is compromised – they haven’t said “yes” but it seems very likely. How an organization comes out looking in these trying times comes down to how they handle their responses – how they improve security posture, how they communicate the extent of the breach to its members, reporting to regulators/investigators, services offered to those concerned about their personal information, how they clean up and recover, making sure it doesn’t happen again, etc. If true, the “ARRL does not store credit card information anywhere on our systems, and we do not collect social security numbers” which helps with regulators and government but leaves privacy minded individuals who do not wish for personal details, albeit “publicly available,” to fall into the wrong hands.

Yes, this absolutely should not have happened. In a perfect world, it wouldn’t have happened. We don’t live in a perfect world and not everyone is perfect despite how some present themselves.

From my own experience, working with vendors and Managed Service Providers (MSPs), it takes a lot of extra work to make sure what they are telling you is correct and make sure what they do is correct. ARRL does use Microsoft services and they’ve had their share of scathing reports of inadequate security practices recently. I work with a lot of different Information Technology (IT) teams. The number of analysts (and management) that know very technical details about systems they are responsible – is remarkably low. When an analyst doesn’t know their system, doesn’t know how modifications affect that system, how would they know if a modification opens their organization to attack? Maybe an employee was thinking they were doing their job but clicked a password stealing link or downloaded a fake invoice containing a malicious payload (malware that performs malicious activity). The latter is often due to a lack of proper training in security practices for general employees. Again, these are only my experiences and observations working in IT.

The ARRL posting has been updated several times as recovery progresses and systems come back online. This disrupted most ARRL IT systems including phone systems, Logbook of the World (LoTW), VEC application processing, some magazine resources, store orders and shipping. LoTW data is “secure” presumably meaning no uploaded contact logs have been lost. The arrl.net forwarding system was not affected but I’ve been moving off it due to messages being bounced previously.

THE TECHNICAL COORDINATOR
Jeff Kopcak – TC
k8jtk@arrl.net

Hey gang,

One thing that has kept me busy this year is work. We’ve been traveling for deployments and other work projects. Pilot sites get someone onsite to make sure the transition goes (relatively) smoothly. In addition, cutovers for other sites and other systems have been occurring off hours – early mornings or late at night. One of the perks of traveling for work is the ability to extend a trip using personal time.

The first trip was an M&A (merger and acquisition) in East Hartford, Connecticut last March. One reason I wanted to extend this trip was because East Hartford is about 15 minutes away from Newington – otherwise known as the location of ARRL HQ.

I like to drive and this was a drive at 9 hours. It ended up being more like 10 or 11 with stops and detours. Extending this trip, partially because of ham radio, and getting to drive means I take a lot more ham radio stuff. I put on music and will switch off listening to VHF & UHF. I have an ICOM IC-2820 radio with a homemade cigarette lighter power cable. Using the cigarette lighter (now called an accessory port) is more than good enough to power the radio especially when listening more than transmitting. Since this wasn’t my car, the install has to be very temporary. Most accessory ports are fused at 10A. That limits me to low or medium transmit power. Low power (5W) draws 4A and medium power (15W) is about 7A (a little less on 2m). No reports of alternator whine either.

I know there are those who make lists of repeaters when traveling. With electronic sources such as RFinder and RepeaterBook, it’s easier more than ever to import repeater data into radio programming software. The Travel search in RepeaterBook makes it even easier by selecting a travel route or highway. A problem with that feature is the repeater owner or a contributor to RB have to tag a repeater as being accessible on or from a particular route. I-80, which I traveled through most of Pennsylvania, only lists 25-2m/440 repeaters end-to-end. I traveled 270 miles of I-80 in PA. That seems low.

Instead, I use band scan memories or scan edge memories. To me, it’s easier than making banks of repeaters for different cities along the way. Scan edges are memories available on most modern radios. Set the start and end frequency and the radio scans frequencies in-between, stopping on any signals received. Once it hits the end frequency, returns back to the start frequency and begins scanning again. These memories are often notated as “xA/xB,” “xL/xU,” or similar memory locations noting beginning and ending frequencies respectively.

The 2820 is capable of dual-band operation with two receive frequencies at one time. On the left side of the radio, I had a scan starting with 144.000 and ending at 148.000, which covers the 2m ham band. On the right side was 440.000 – 450.000 for the 70cm ham band. The “step” setting determines frequency increments. 15.0 kHz step starting on 144.000 will then scan 144.015, 144.030, 144.045, and so on. A step of 5.0 kHz starting on 144.000 will then scan 144.005, 144.010, 144.015, etc. Most 2m ham band repeater plans are 15 kHz and 25 kHz on 440. I stick to those as my step settings.

W1AW digital equipment Rack 1: APRS/D-STAR/HF MARS. Rack 2: Demo. Rack 3: Echolink & Winlink. Rack 4: IRLP

Setting the step to 5 kHz catches more transmissions in cases where a repeater might be coordinated on a non-standard frequency or simplex conversation had on a weird frequency. It does take much longer to scan and the radio will stop on much more interference from the car or other near-by transmitters. Not worth it to me setting such a small step value.

In this day and age, noise will be an issue and the scan will stop frequently. Stopping frequently can be further reduced by turning up the squelch or attenuator, but you’ll miss weaker signals. Some radios have a ‘skip’ (sometimes called “lock-out”) function that will skip over problematic frequencies. I use the radio’s “scan resume conditions” to resume scanning 10-seconds after arriving on a signal. This is nice so I don’t have to keep messing around with the radio while driving. If there is an interesting conversation, it’s one button to stop the scan to remain on that frequency.

Before someone says ‘you should have flown,’ a co-worker did fly out of Cleveland. Since there are no direct flights to Connecticut, he flew from CLE to ORD (Chicago) then onto Connecticut. With layovers and delays, he left the same time I did from Cleveland and arrived only an hour sooner than I did. If I would have cut out my own detours made in New York, probably would have beat him there.

Unfortunately, this was a grueling trip. Driving wasn’t really bad until I got to Scranton, PA, but it was still a lot of driving. We were on site Friday through Tuesday, working 10-to-12-hour days. Didn’t do much operating on the front end of this trip. Once we ate and got back to our rooms, it was time to get some sleep and do it all again the next day. We got it done, though. Left the site Tuesday a little after 2pm and tried to catchup on rest. I planned a ARRL HQ visit the next day, Wednesday, March 20th.

I took a bunch of pictures outside of the towers and arrays. Apparently, they don’t give tours of HQ anymore (except virtually). I was pretty disappointed. When they did give tours, you could see things such as the ARRL Lab, testing equipment, ham radio archives, and outgoing QSL Bureau. Not to be had this time. Headquarters lobby and bookstore were open and the only parts accessible.

On my last visit with the family, by the time we got to the visitor’s station – W1AW, storms were on their way in. I made calls on HF but made zero QSO’s before NJ1Q had to shut down the station. Being one of my first few times on HF was really bummed not to make any QSO’s and learn how things worked. A year after that trip, I got an HF station setup at the home QTH – which my dad had a big hand in setting up.

Studio 3 operating positions. I operated as W1AW from the station at left.

This time was quite different. No storms to worry about. I had over an hour – probably an hour and a half – operating as W1AW in Studio 3 with a Yaesu FTDX9000D, Heil Microphone, and Alpha 9500 amp running about 600 watts. I don’t remember which antenna/array they had be working on. Operated mostly on the upper part of 20 meters, around 14.290. Changed frequencies once or twice to avoid other stations that were coming up out of the noise. Had a great path into Ohio as I worked many stations from the Section. Those in Northeast Ohio informed me I missed the two inches of snow. Dodged that bullet. Unfortunately, didn’t note exactly how many contacts I made. I had 40+ contacts after an hour, probably 50 or so QSOs in total. If you happened to make contact, QSL cards are available direct to the ARRL HQ mailing address.

I had such a good time operating that I stuck around even longer and talked with Joe, NJ1Q – Station Manager and Trustee. Fascinating person to talk to. He had finished testing, fixing, and was packing a portable station for a school contact with the ISS in Colorado. Spoke to him about their digital setup including Winlink station. I’ve previously used W1AW on HF to exchange messages from the home QTH. “It must be working,” said Joe. It sure is. Wish I had their racks of digital equipment in my shack and towers in my backyard. He also gave me some tips for things to try with some issues I am having. A veritable fountain of wisdom.

For being at the visitor’s station, you now receive a certificate for either visiting or operating. Remember to bring a copy of your valid amateur license in order to operate. The certificate was something carried on since the centennial 10 years ago. I didn’t receive one on my last visit. We figured out it had been 11 years (2013) since my last W1AW visit and certificates started just after that.

The remainder of that trip was non-ham radio activities. One of the wide-area linked repeater systems with 10 sites had a pretty bad hum. The owner and some users were trying to track it down. I don’t own a repeater but it is a thankless job.

Snapshot from video I took – near the end of totality, 4/8/2024

Couple weeks later, I was in Waco, TX. Since I was flying, I took the IC-91AD HT with me but didn’t have much time to use it. I take hardly any ham equipment when I fly because I don’t want to deal with TSA.

Waco was in the path of totality for the April 8th Eclipse. I thought about extending the stay but decided against it. Good decision because they had storms. Contacts at the site wanted to see my pictures from Ohio because it turned out to be a crummy day for them. I also heard car rentals were up around $600/day in Dallas.

Speaking of the Eclipse, I took the day off and contributed to HamSCI by transmitting and uploading spots for WSPR. I had to make preparations to get my camera setup and had family coming over. Since I wasn’t seeing many special event stations on the DX Cluster in the morning, left the radio to do WSPR spotting. Maybe HamSCI will be at Dayton/Hamvention and I’ll talk to them about the data gathered from Ham Radio stations.

THE TECHNICAL COORDINATOR
Jeff Kopcak – TC
k8jtk@arrl.net

Hey Gang,
I don’t have to complain to you about the hot and extremely humid weather we’ve had because all of you are living it too. Storm season arrived later in Northern Ohio. I wrote last month how my city got hammered by some storms. It continued with a tornado outbreak in Indiana on August 24th. Friend and regular checkin to the Ham Nation D-STAR net luckily sustained no damage. However, his neighbors a quarter-mile to the north and south had their homes destroyed. The line of storms that moved through Indiana spawning many tornados prompted the National Weather Service in Cleveland to staff the Skywarn desk. I was one of the operators at NWS that night. Though the storms significantly weakened by the time they reached the Toledo area, there was one confirmed EF0 tornado in Pemberville (Wood County – my old stomping grounds). It touched down along route 6 and dissipated quickly but not before removing sheet metal roofing from nearby buildings. No injuries or fatalities.

Public service season is quickly wrapping up for most of the section. Technical Specialist David KD8TWG ran much of the five-day public service event at the Great Geauga County Fair. Being from Cuyahoga county (and the far west end at that), I was a little skeptical. ‘OK the GREAT Geauga Fair.’ But it really was a great fair. It’s the biggest one I’ve attended. There’s a ton of people, displays, awards, animals, events and acts, and yes people really do stand in line 45 minutes for a milkshake. This was confirmed in a casual conversation between fair-goers. As far as ham radio there is a great mixture of technologies including Ohio MARCS, 800 MHz, APRS, Mesh, VOIP, and a portable repeater for their communication needs. It was quite the elaborate setup and really is a great example of utilizing technology to suit communication needs.

The public service season concluded in Cleveland on the 11th with a half-marathon called “River Run.” It was great weather and there wasn’t a single ambulance call. A lot of the ham radio event coordinators have to beg, twist arms, and make many phone calls to get people to come out and help. Please volunteer and help out with these events. You’re there to make sure everyone has a good, safe time during the event. Your presence also gets ham radio out in front of the public and builds relationships with event organizers and county officials. If you’re active in helping out with public service events, you’re more likely to be called in the case of an actual situation.

Ham Nation episode 264 (https://twit.tv/shows/ham-nation/episodes/264) was an episode that featured an all YL cast. Everyone on the show that night was a young lady. The episode highlighted female participation in the hobby and pointed out that ham radio is not made up entirely of OMs. Additionally, Dr. Skov (who is not licensed … yet) gave a detailed tutorial on ionospheric conditions and how space weather effects propagation on the HF bands. She talks about the atmospheric layers, electron density, how those layers change during the day vs night vs gray line, the layers which reflect signals, Kp and X-Ray Flux indices. Her tutorial would have really helped me on those licensing test questions! It starts about 44 minutes into the episode – with some interesting analogies. I will leave it at that!

I’ve been spending a ton of time learning more about the DV4Mini and DMR in particular. The DV4Mini is a USB hotspot device about the size of a large USB memory stick. It has the ability to “speak” several different digital modes: D-STAR, DMR, Fusion, P25, and dPMR/NXDN/IDAS. A hotspot is a device that provides connectivity. In this case, to different digital networks from your home PC or Raspberry Pi with a low powered transmitter (usually under 10mW). A misconception I hear a lot and have been asked about: yes you do need a radio for each digital mode you want to operate. To connect to D-STAR reflectors you’ll need the hotspot device and a D-STAR capable radio. Similarly, for DMR talk groups, you’ll need the hotspot and a DMR capable radio. I’ve been hanging out a lot on the Ohio Statewide talk group (3139) and USA Nationwide (3100), I even ran into our own Section Manager on the network!

The more time I spend with the DV4Mini the more issues I find with it. It’s a great concept to have one device to work 5 different modes. The DV4M has a lot of issues that I hope the developers correct related to its performance. I actually bricked mine updating it to the latest firmware. Had to crack the case and put into bootloader mode to re-flash the firmware. The update took the second time. This happened to another user too. Comparing audio quality to repeaters on the network and listening to BrandMeister Hoseline, the audio from the device sounds bad most times and terrible the rest. The direct calling feature doesn’t seem to work. A buddy of mine found the developer for the BrandMeister extended routing feature (DV4MF2) completely ceased development as of September 9th. It will be interesting to see why that happened and if that means anything for the future of the device. There are other hotspot devices out there and I hope to find out more about them soon.

David KD8TWG and his presentation on APRS at the Lake Erie Amateur Radio Association (LEARA) meeting was fantastic. We had a lot of fun with APRS on our smartphones and radios sending messages back and forth.

Thanks to the Cuyahoga Amateur Radio Society (CARS) for having me at their meeting on September 13th. I presented my introduction to the Raspberry Pi computer. Good discussion ensued in both cases on new technology hams can utilize.

Coming up, I will be at the Cleveland Hamfest on the 25th. Two days later I’m giving a presentation at the LEARA meeting on Slow Scan TV. If you’re in the Cleveland area and want to see SSTV in action, stop by the meeting on the 27th. More details will be available at leara.org as the meeting date approaches.

Congratulations to Scott N8SY on being reelected as Section Manager for the Ohio Section. Give him a pat on the back or buy him a beer when you see him for all his hard work!

Hey Gang,

As I’m beginning this month’s article some nasty storms just ripped through Cleveland on the 11th. There were branches, trees, wires, power lines down, and road closures on the west side due to those hazards, including my QTH of Westlake. Luckily I’ve heard of no injuries. If you’re not part of the NWS Skywarn program, please consider joining as a spotter. Skywarn is a volunteer program that helps the local National Weather Service office know what’s happening on the ground and assists in warning people about dangerous weather conditions. Training typically happens in the early spring for spotters. Check with your local club or Skywarn organization.

The Republican Nation Convention went off without major incident in Cleveland. I was working from home and had the scanner on most of that week. Three major trunked radio systems were utilized: MARCS, the new MARCS-IP (Multi-Agency Radio Communications System), and GCRCN (Greater Cleveland Radio Communications Network). If you didn’t set a wildcard or use UniTrunker to watch those systems, you probably missed a lot of the event communications. There were about 12 primary talk groups on GCRCN where most of the action took place. These were previously unidentified so they were not in any lists or databases that use Radio Reference. A wildcard stops on any talk group whereas programming specific talk groups into the scanner will only stop on transmissions for those talk groups. The “old” MARCS system was shut down immediately following the convention as it was kept online largely for backup. It has been replaced by the MARCS-IP system.

This month we learned the sad news of Hara Arena’s closing. No more Hamvention at Hara Arena after 52 years. The Dayton Amateur Radio Association put into action their contingency plans. It was announced that Hamvention will still be in the Dayton area. The new location is The Greene County Fair and Expo Center located in Xenia, Ohio. Michael Kalter and Ron Cramer talked about the new location on Ham Nation for about 30 minutes in episode 259. Couple of links worth visiting:

One of our Technical Specialists, David KD8TWG, has been involved with setting up a DMR repeater in Cleveland. The frequency is 442.0875 (+5 MHz standard offset) using Color Code 1. The repeater is connected to the K4USD cBridge (http://www.k4usd.org/). On that website is a listing of the “standard configuration” for repeaters connected to the bridge. Right now, your code plug should follow the layout listed on the site. A cBridge is a feature that allows interconnecting of repeaters over the Internet and a Color Code is equivalent to a PL tone or DCS on analog repeaters.

When I picked up my DMR radio at Dayton, I found a code plug that had repeaters in Dayton and Columbus for the drive home. It was a nice opportunity to quickly get on the air with DMR but I kept threating myself to write my own. With the installation of the repeater in Cleveland, I took the opportunity to do just that. What is a “code plug?” Some history I found online notes the origins came from wire plugs, later jumpers, which were plugged into the radio to enable certain options or features. Since everything is now processor based, the term continues to stick with the radio world and is a fancy word for ‘radio configuration.’ It contains transmit/receive frequencies, tone selections, timeout values, IDs, configuration settings, etc. I used the one I found in Dayton as a reference. There is also a sample one on K4USD’s site for my radio. I compared the two and designed mine the way I thought worked best. Just because someone designed a code plug one way doesn’t mean you can’t modify or do it differently. It’s analogous to one ham’s memory channels are not the same as another. In the end, it took about 3 hours to make mine! Keep in mind that was a lot of learning and comparing, in addition I programmed all 65 possible talk groups so I don’t have to add them in later. From discussions on the air indications are it took others a few hours as well. But my code plug works! I couldn’t be happier. Well OK I could, apparently I’m just far enough away that my 5 watts doesn’t quite make the trip. I took the radio to work and tested it from there.

I am writing an introductory series for the Wood County Amateur Radio Club on getting started in digital modes. The first few articles were for those who have never worked digital and want to upgrade their station. Remaining articles will focus on a specific mode. I’ve completed 3 so far (starting in February): an introduction, station setup, and working JT65/9. Published versions can be found at the club’s website in the CQ Chatter newsletter: http://wcarc.bgsu.edu/. As I point out in the second article, Technician class licensees can still participate. All of these sound card digital modes can be operated over FM simplex or even a net on a repeater using an HT! There are clear downsides like not being able to transmit as far as an HF station and occupying the full 10 to 15 kHz FM, even though the bandwidth of the audio generated by the computer is less. Yes, this defeats the purpose of narrow bandwidth modes. Someone wanting to learn and experiment with these modes may get bitten by the bug and lead to a license upgrade. That’s how I did it. I plan to write an article every 2-3 months.

My dad and I had the opportunity to join the Toledo Mobile Radio Association (TMRA) on August 10. They had Chris Wilson N0CSW, National Sales Manager for Yaesu talk about their System Fusion. Chris did make it clear that the company was paying for travel so there would be some ‘sales pitches.’ The presentation was short but the program ended up being driven by the audience with a lengthy question and answer session. Some things I learned: the DR-2X repeater announced at Dayton is not going to be a replacement for the DR-1X, though they may have improved on some shortcomings. The 2X is more of a full featured repeater. It will have the ability to operate dual receive and dual transmit (but not at the same time) creating two repeaters from one unit. They are including voice messaging (like club meeting announcements). Mailboxes were users can record messages for others. This reminds me of the mailboxes repeaters used to have when autopatches were more prevalent. The 2X can monitor a separate control channel for commands. This repeater will not support WiresX but will have “MSRL” (Multi-Site Repeater Linking) via an add-on Ethernet port. Their linking technology will allow the repeater to be linked over any IP based network, including mesh. This brought to mind an interesting use-case where multiple low profile/portable repeaters could be linked at sites with mesh such as air ports, hospitals, and Red Cross shelters. This would create a linked repeater system where not as many users would have to setup cross-banding or run to the other end of a hospital to reach a radio. In contrast, something similar can be done using the AllStar Linking system. At the meeting there was alot of: “I would like this feature/I don’t like this feature in the radio,” “we’re having this problem setting up the repeater to do X” kind of Q&A. My take away from that, their plan is to add features to radios by firmware update and not always release new radios.

In addition to all the work David KD8TWG has been doing to get DMR up and running in Cleveland, he’s been helping repair and upgrade analog repeaters, and setting up APRS IGates around town. He will be giving a presentation on APRS at the Lake Erie Amateur Radio Association’s club meeting on August 30th. Dinner starts at 6:30pm with the meeting at 7:30, don’t need to have dinner to attend the presentation. Haven’t seen an official announcement on location yet but it’s expected to be at the Play Arcade in Mayfield Hts (5900 Mayfield Rd, Mayfield Heights, OH). Check the LEARA website for updates and for dinner reservations: http://www.leara.org/.

I will be giving my introductory Raspberry Pi presentation at the Cuyahoga Amateur Radio Society meeting, September 13 at 7:30pm. It will be updated as there is new hardware and innovations available. Their meeting location is the Busch Funeral Home, 7501 Ridge Rd, Parma, Ohio. More: http://www.2cars.org/.

Hey Gang,
It’s been a busy month with ham radio holidays and national holidays. June was a great operating month for me as I had taken some time off work after Dayton. Since I really hadn’t been on the air the first half of the year, I spent a lot of time catching up. Heck April I made a total of three contacts. Bleh. I racked up 130 contacts including Field Day and 17 National Park activations. As usual I’m coming to the party late on NPOTA so I’m getting there. Our own Affiliated Clubs Coordinator John KD8MQ has given many updates in past editions of the Journal; check them out. More: https://npota.arrl.org/

I will tell you no matter what you do for Field Day, you’re always going to have a good time. If you get together with a club or some buddies, there are going to be good stories too. This year I took a different approach and decided to operate as a 1D station. Still had a good time. It gave me a chance to refresh my memory and practice using the Digital Signal Processing (DSP) and filtering features of my radio. As one would expect, there were stations all over the place. The bands weren’t that great either. I would hear a station but not clearly. I used different Automatic Gain Control (AGC) settings, Noise Reduction, filters, Passband Tuning (PBT), the whole nine yards. If I wasn’t hearing much scanning around, I would go work on something else and come back later to work more stations. In total made 30 contacts mostly on 40m from the home QTH.

The following weekend was Canada Day and the Independence Day holiday weekend. First up was the Radio Amateurs of Canada (RAC) Canada Day contest on July 1st. Since I’m a station outside Canada, the exchange was RST and serial number. The serial number was the number of Canadian stations worked during the contest. I worked 14 stations total over the 24 hour contest.

Then (of course) starting Friday morning was the 13 Colonies Special Event. There is one station in each of the 13 original colonies and two bonus stations. Bonus stations are Philadelphia where independence was declared and England for the “British Standard” contact. Things were going well for me. I started out working 9 stations on Friday night and 5 on Saturday morning. Then nothing. The British bonus station was eluding me. I kept trying when they were calling on sideband but they never came back to me or by the time they went through the numbers and got to 8 – they were down in the noise. It wasn’t looking good. In literally the 11th hour, I finally made contact with England on PSK for my clean sweep! I’ll be sending away for my certificate and sending out QSL cards soon. If you worked any of the 13 colony stations, please support them by making a donation or sending in for a certificate. Many stations took time out of their holiday weekend to put on another successful event. More: http://www.13colonies.info/

Last month I mentioned the Portage County Amateur Radio Service was going to have an Earth-moon-earth presentation for their July meeting. I’ve never experienced or knew anyone that worked EME so this was a presentation I did not want to miss. It was a bit of a drive in rush-hour traffic from downtown Cleveland. Nonetheless, food was great and it was an excellent presentation. Tony WA8RJF talked about the properties and theories involved making EME contacts, early days of EME needing monster arrays with gain antennas and rotor controls the size of two truck-beds –in one case. Then he talked about JT65 being the game changer to make EME communication more accessible to regular hams. The majority of my HF contacts are JT65 so a lot of it hit home for me. JT65 was originally created for EME but later adapted to HF and has become the second most popular digital mode. Thanks to Tony and PCARS for allowing me to be a guest at their meeting.

Speaking of modes I haven’t yet operated, the QSO Today podcast interviewed Art Towslee WA8RMC of Westerville who is heavily involved with ATV (Amateur Television, sometimes called Fast Scan TV). ATV uses video and audio much like a commercial broadcast station. In many ways you are operating from your own studio with a video camera, microphone, lights, or other video sources. In the podcast they about Art’s history, knowledge, and involvement in projects to move ATV forward using Digital TV standards. With the introduction of Digital TV, quadcopters and 4K resolution, ATV is becoming popular once again. Slow Scan TV in contrast is sending a single still image over the air.

The TAPR Digital Communications Conference is coming up September 16-18 in St. Petersburg, FL. The list of speakers and forums haven’t yet been released but topics will likely include Software Defined Radios, digital voice modes (D-STAR, Fusion, DMR, P25, Codec2, FreeDV), digital satellite communications, APRS, and the like. More: https://www.tapr.org/dcc.html

In a great article from ARS Technica, they talk about the Linksys WRT54GL router that is 11 years old and still making millions for Linksys. This router came out in 2005 but really had an ecosystem built around it. The router was Open Sourced making it easily modifiable and turning it into a much more powerful router. We hams have seen this first hand as these are one of the more popular models used in Mesh Networking. Linksys said they’ll continue to make the router while suppliers keep selling the parts; great news for Mesh users. More: http://arstechnica.com/information-technology/2016/07/the-wrt54gl-a-54mbps-router-from-2005-still-makes-millions-for-linksys/

On a sad note that hits close home, especially those in Cleveland. At the end of July, Amateur Radio equipment retailer Amateur Electronic Supply (AES) will be closing for good. We all have stories about the long time retailer. I liked browsing the show room and playing with the radios on display. They were always helpful to their customers. It’s sad to see a retailer leave and friends lose their job. 73’s to the AES crew. You will be missed. More: http://www.arrl.org/news/amateur-electronic-supply-closing-after-59-years-in-business

That’s about it for this month. With the conventions going on in the state, everyone please stay safe. As I’m writing this a few days before the RNC, there are plenty of changes happening in Downtown Cleveland: unmarked SUVs, helicopters flying around, “Cell on Wheels” (COW, portable cell sites) popping up, temporary stages going up, and TV equipment trucks. My company has made previsions for us to work remotely. Those with a P25 digital trunked capable scanner in the Cleveland area will probably find most activity on the Ohio MARCS-IP (Multi-Agency Radio Communications) and GCRCN (Greater Cleveland Radio Communications Network) systems. The old MARCS 3.5 legacy system is going to be kept on-line as a backup to the MARCS-IP system. After the convention that system is expected to be fully shutdown. No definitive word on talk-groups to listen to but keep an eye to the Radio Reference Ohio forum and frequency database pages as things gear up.

Hey Gang,
You’re reading this so you survived another Dayton. My dad N8ETP and I went down on Thursday. We stopped at MCM Electronics. It was actually on the way because we stayed south of Dayton this year. My dad was looking for some parts. I ended up buying another Raspberry Pi 3 on a Dayton weekend special and an Arduino Uno board. The Arduino was cheap and a lot smaller than I expected. Don’t have much lined up for it but I did want to try a project I saw on AmateurLogic.TV some time ago.

The difference between the Raspberry Pi and Arduino Uno boards is the Pi can run a full operating system (usually Linux) while the Arduino Uno runs instruction sets uploaded to memory. Variants of the Arduino can run entire operating systems. Both have General Purpose Input/Output (GPIO) pins for interfacing. I haven’t mentioned it in this space – Raspberry Pi 3 is the latest addition to the line of cheap micro-computer devices. The Pi 3 has all the features of the Pi 2 with an upgraded CPU to 1.2 GHz 64 bit, built in Wireless N LAN, Bluetooth 4.1 and Low Energy (LE). All of this goodness (still) at $35 in the same form factor. I ran a compile of Fldigi/Flmsg for comparison. The Pi 2 compiled the programs in about 22 minutes, the Pi 3 compiled in about 13 minutes.

This year I really didn’t have a lot on the Dayton shopping list. I wanted to take a look at the new ICOM IC-7300. That is a very nice radio and a huge improvement over my IC-7000. I didn’t pull the trigger on that for some reason. I’m reluctantly holding off. The newer radios are coming with built in USB. For someone looking to get into HF digital check out the newer radios. You won’t need a SignaLink type device because the sound card is built in!

I did attend Dayton with the intent of purchasing a DMR radio. From the amount of people I heard on DMR repeaters and podcasts afterwards, it sounds like they were the popular item this year. For good reason, I picked up a Tytera MD-380 for a little over $100. It included the radio, battery, charging base, 2 antennas, programming cable, and software.

DMR stands for Digital Mobile Radio and is a standard published in 2005 that came from our friends in Europe. It is an open standard (publically available for adoption and modification) and widely adopted for commercial use. In practice manufactures have introduced proprietary features into DMR and created marketing buzzwords like MotoTRBO. With enough surplus hardware available in the market, the price dropped low enough for hams to adopt the standard and setup DMR repeaters. I have a lot to learn about how all this works. There aren’t DMR repeaters in range of my QTH. Couple on the opposite side of town and to the south. There are some repeaters in Toledo and Columbus. The greatest concentration is between Dayton and Cincinnati. Thanks to the folks at the Dial Radio Club in Middleton, Ohio, I had a DMR repeater easily accessible from my hotel room during the show.

New things I saw include scanners from Whistler with DMR (expected June 2016). Following quickly behind was Uniden with the same announcement (no release dates set). If you have a public service agency utilizing a DMR system, you’ll soon have scanner options available. Kenwood showed off their 2m/220/440 radio with APRS and D-STAR (and hopefully DPRS). My dad and I both noticed how incredibly crisp and clear the color display was. Standing about 5-6 feet away we could easily read it. Wireless Holdings showed off a new digital all-in-one radio, the DV4mobile. This thing has ALL the features: 2m/220/440, DSTAR/DMR/Fusion – with P25/NXDN/NEXEDGE coming next year, LTE (as in cellular connectivity), remote programming, remote operation, Ethernet/WiFi, SMS (text messages). Will this thing do my dishes too? Wow. Both Kenwood and Wireless Holdings are expecting release dates in about 6 months.

Thanks to everyone who stopped by the Field Services table at the ARRL Expo. I had a great time chatting with hams from England and exchanging ideas. It was fun meeting those in Newington who administer the programs we know and love. A lot goes into these programs and there’s a lot of technical research happening. The table was staffed by representatives from the Ohio Section including moi. Scott and his wife Jane spent most of the show at the table making sure everything went smoothly. Huge thanks to them for getting everything organized. It was nice to meet all of you. I picked up a couple books in the store on the way out. More stuff to do!

Reminder about Windows 10: Don’t forget the free upgrade offer to Windows 10 is set to expire July 29th. You still have about a month to decide on the upgrade. If you missed my April article, I went into great detail about Windows 10 and the push to upgrade users. Check it out on my site or on the Ohio Section Journal site. There is no indication from Microsoft if the upgrade will become a premium option or if they will extend the offer. Some analysts think it will become a pay upgrade others think the upgrade offer will be extended indefinitely. One change, Microsoft is becoming even more aggressive in forcing the upgrade. Didn’t know this was possible but they’ve succeeded. I mentioned in April that clicking the red “X” to close the upgrade pop-up will delay the upgrade. This is no longer true. Microsoft’s new interpretation of clicking the red “X” is an AGREEMENT to the upgrade. This whole upgrade thing is ridiculous. I have no defense for this behavior. If you want to disable the Windows 10 upgrade, run Never10 (https://www.grc.com/never10.htm). Many users are disabling Windows Update to prevent the upgrade. Please don’t. If you have, run Never10 and disable the upgrade. Reboot. Check it’s still disabled by running Never10 again. Run Windows Updates and let it do its thing. Then run Never10 again to verify the upgrade is still disabled. I’ve been upgrading my machines to Windows 10. It takes some finessing to disable the crap. I do keep coming back to a single question: “why?” Not ‘why did I upgrade’ but ‘why is this useful setting now burred and takes fifteen clicks when it used to be three’ or ‘why would you change things (color schemes, color contrasts, move things around for the seventh time) just to change things?’ Haven’t yet taken the plunge to wipe-out my machine in the shack.

Technical Specialist report:

With summer and projects gearing up, requests have been coming in. Bob K8MD and a good friend of his Dave NF8O traveled to the Ohio Veterans Home station, W8OVH, in Sandusky. They have a sideband station and wanted an upgrade to run digital modes. Bob and Dave spent a few hours working with them to get the station up and running. They trained the club members how to use Fldigi and helped them make their first PSK31 contact! The guys reported it was a humbling experience talking to Vets who served in major conflicts from WWII to Grenada.

Dave KD8TWG has been busy with presentations for ARES groups. First was a presentation on APRS for Cuyahoga ARES. The presentation touched on history, uses, settings and what they mean, and systems built on the APRS network. There is a lot to APRS and I learned a lot. Soon after he did a “program your radio without a computer” for Geauga ARES. Interesting concept. Most groups bring computer programming in to help newbies program their radio. Knowing how to program a radio without a computer is useful during an event or public service activity where improvisation is likely needed. Could you change PL tone on your radio and save it in memory though the front of your radio? Programming a temporary repeater that has a 1 MHz split? DCS, anyone? It’s good to know and practice changing transmit, receive, PL frequencies, and power settings on-the-fly through the front of your radio.

PCARS (Portage County) club members contacted me about a moon bounce (EME) presentation. This is an area I wasn’t familiar with or knew anyone who operated. I reached out to the assembled mass of Technical Specialists. Tracey – W8TWL came through with a couple contacts. Got PCARS in touch with one of them and they are working out the details for the July 11th meeting. I’m hoping to make this meeting and see a great presentation on Earth-Moon-Earth.

Hey Gang,

I’ve wanted to do this article for some time but kept putting it off due to more relevant and timely topics. Ham Radio Podcasts. With Dayton quickly approaching, you’re likely to see many of these hosts at Hamvention. If you’re not, you may have seen them in the past and wondered “what’s a podcast?”

The word “podcast” is a mashup between the words “IPod” and “broadcast.” There is some debate on this because the word predated the IPod portable media player. Some say ‘POD’ means “portable on demand.” Either way, they are both accurate. “Net cast” is an Internet broadcast and synonymous with podcast but typically don’t make content available offline.

A podcast is a digital media file offering audio and/or video content. PDFs or eBooks (books in electronic form) can be considered podcasts too. In general, podcast refers to audio or video. The content can be whatever the creator wants each file to contain. Most are a series of episodes covering a topic of interest. Some follow a news magazine format discussing recent news and developments. Others could be clips from a longer radio show including interviews or bits made available for download. Podcasts often serve niche interests where it might not be popular as a broadcast radio show to the general public. The same content targeted toward special interests or hobbyists would do very well.

The creator or distributor maintains a list of episodes known as a “web feed” which provides users with updates. RSS (Really Simple Syndication) is used to publish frequently updated information. The RSS rippling signal icon with headphones or microphone signifies a podcast feed. An app known as a “podcatcher” monitors the web feed for new content. The app then notifies the user or downloads the episode automatically. Once the file is downloaded, it’s available offline where you don’t need to be connected to the Internet. In this way someone can download a number of episodes and listen to them at a remote camping site with no Internet. This is different than YouTube or Netflix where a connection to the internet is required to view content on demand.

The first podcast was believed to be released around 2003. This technology really became popular with the growth of the internet and portable media devices like the IPod. Podcasts cover a vast range of topics including: movies, news, science, comedy, interviews, storytelling, health, love, self-improvement, music, food, business, sports, pop culture, and farming. The list… goes on. There really is something for everyone. Podcast technology is considered disruptive because the radio business spends a lot to provide content to wide-ranging audiences. Podcasts have shown that preconceptions of audiences, production, and consumption are no longer traditional. Sure some podcasts are produced in studios with professional equipment. The majority are recorded using similar pieces of gear found in your ham shack: professional microphone, mixer, computer, internet connection to bring in guests, and maybe a video camera or webcam thrown in there too. Anyone can do it!

On the flip side, since anyone can do it, episodes depend on schedules of the host(s). Some release on a weekly schedule, some monthly, others “as time permits.” Some podcasters have been around awhile. While others try it out and decide it’s too much effort.

I consume podcasts using my phone. If you do the same, know the limits of your phone’s data plan and use Wi-Fi when possible. Video files in particular can be very large depending on quality (hundreds of megabytes to a gigabyte). Podcatcher apps are available on every platform. Check the ‘app store’ for your device. PocketCasts is my favorite. It’s available on Apple and Android devices for about $4. I think it’s the nicest looking app and it’s easy to discover podcasts. Stitcher is another popular app, and free. Apple ITunes, Google Play, and TuneIn have podcast directories. Poddirectory (poddirectory.com) is great for desktop users. Also devices like the Roku, Chromecast, and Apple TV allow for viewing on a TV.

Podcasts are free. Many are supported through sponsors. In the same way that podcasts are targeted for special interests, the ads typically are too. Some ask for support and donations in lieu of advertisements. Others don’t ask for any support. If you find any podcast useful or you regularly listen, show your support for the work they are doing by throwing them a couple bucks or visiting their sponsors. It does cost money for equipment, bandwidth, storage, projects demonstrated, and services needed to bring you a wonderful podcast.

THE TECHNICAL COORDINATOR
Jeff Kopcak – TC
k8jtk@arrl.net

Hey Gang,

So — Windows 10. This topic was brought up during the after meeting at my local club. Many of you are undoubtedly seeing the upgrade nag-screens. You too might be wondering: what’s changed in Windows 10, might have heard some of the issues surrounding the new operating system, and why the big push to upgrade. This month I’ll cover the new operating system from the perspective of what has happened so far and not from a ham radio perspective. Also to preface this whole thing, Microsoft has never been very clear about their statements and often retracts or goes back on things they’ve said. In other words, any of this may change as we go along.

What is Windows 10?… why not Windows 9? There are many theories surrounding the choice in numbering. The named version of Windows hasn’t matched the real version number since Windows NT 4.0. Windows 10 is the successor to Windows 8.1, but not Windows as you know it. It represents a shift in the direction of Microsoft as a company. Microsoft indicated this is the “the last version of Windows.” While they’re not killing it off, Microsoft is moving to a model they call “Windows as a service.” This means Microsoft will deliver innovations and updates in an ongoing manner instead of separate releases (versions) of Windows. The ultimate goal is to have one version of Windows that will run on all platforms. Everything, including Raspberry Pi, phones, tables, HoloLens (wearable, so called “smart-glasses”), laptops, desktop PCs, Surface Hubs (interactive whiteboards), and Xbox entertainment systems. Having one version of an operating system means all of these systems will become integrated and share information easily.

A large part of this shift includes the use of “the cloud.” The cloud is a fancy term for someone else’s equipment on the Internet. The most common example is ‘cloud storage.’ Services like DropBox, Google Drive, or OneDrive allow you to save your documents and pictures elsewhere. You upload files to these services and you can access those files or share them with others on the Internet. The cloud is heavily integrated into Windows 10. After installing Windows 10, it will prompt you to sign in using a Microsoft Account. This syncs your user profile with the Microsoft cloud. When you sign into another device using your Microsoft Account, your settings will be the same across those devices. You can use Windows 10 without a Microsoft account. The computer will operate in standalone mode similar to previous versions of Windows. Microsoft’s online storage service called OneDrive is integrated into the operating system as well. Other new features include your new personal assistant, Cortana. She will help find things on your computer and the web, set reminders, similar to Apple’s Siri or Google Now.

Universal apps: These first appeared in Windows 8 as “Metro Apps.” This concept is to have developers write one application and have it work the same way on any Windows platform. These apps are found and delivered via the Microsoft Store (similar to the Android Play Store or Apple’s App Store), and again – available on all platforms. Some games and applications that came preloaded in previous versions of Windows have been replaced with Universal Apps in 10.

Edge browser: Microsoft Internet Explorer has been replaced with Microsoft Edge. It’s been touted as a more secure browser. However, this has yet to play out because browser extensions are very limited.

Free upgrade: Legal copies of Windows 7/8/8.1 are eligible for a free lifetime upgrade to Windows 10 until July 29, 2016. There are some stipulations to this free upgrade. “Lifetime” means the lifetime of the device eligible for the free upgrade. When that device fails, you cannot transfer the free upgrade to another device. What happens after July 29th? Microsoft hasn’t said. The free upgrade is expected to become a premium upgrade that you’ll have to purchase, even for a device that was previously eligible for the free upgrade. Versions prior to Windows 7 are not eligible for the free upgrade. To be honest, if you’re running a version of Windows prior to 7, you probably want to upgrade your hardware for 10.

Now reality.

Big upgrade push: Windows users have seen the icon in the system tray nagging them to upgrade. Why the big push? Microsoft is trying to avoid another Windows XP. At the time Windows XP was declared “end-of-life,” it accounted for about 10% of all computers on the Internet. Two years later, about 7% are still using XP. That’s a lot of users running a dead operating system. On top of that, Windows 7 will be 7 years old in July and only supported for 4 more years (until January 2020).

While Windows XP maybe working great, there are reasons to get off of it. Google has been leading a push for a more secure Internet. Windows XP cannot handle many modern security methods in use today. All browsers in XP (except Firefox) will display ‘your connection is not private’ when connecting to a website that has more modern security then XP can understand. Since Windows XP is not a supported operating system, it won’t be updated to handle modern security methods. While the website will still work, your connection will be less secure. A work around for this security issue is to use Firefox. Though no known vulnerabilities exist in XP, best practice dictates users should remove unsupported operating systems from the Internet if it doesn’t need to be on the Internet. Another reason to upgrade is new hardware and software will not have support for old operating systems.

The upgrade push for Windows 10 has been nothing short of a disaster. Last year, users eligible for the upgrade began seeing a Windows icon in the system tray saying ‘you’re PC is ready for your free upgrade.’ This deplorable tactic is commonly used by malware and spyware authors to trick you into installing software you don’t want or need. As an Information Technology professional with an interest in cyber security, this is the type of message I tell users NOT to acknowledge. Kind of ironic. Initially this tray icon came in the form of a Windows “Recommended” update. Then Microsoft upgraded it to a “Critical” Windows Update -yet another deplorable tactic. Despite this maneuver, Windows 10 is NOT a critical update. The upgrade popups are very confusing as the clickable options are: “upgrade now,” “upgrade later,” “OK,” or “Get Started.” Oh, it gets worse. Users are reporting they vigilantly closed the prompts to upgrade (clicked the red “X”) but their system was still upgraded automatically against their wishes. They went to bed with Windows 7 and got up the next morning to Windows 10. Surprise.

Once the upgrade happens, you do have 30 days to revert back to your previous version of Windows. The problem here is users have found the roll back frequently fails. Imagine that. ‘Don’t worry, you can go back… if you want. Opps, the roll back just failed! Guess you’re stuck.’ Thanks.

Start Menu: Microsoft tried to remove the Start menu in Windows 8 and replaced it with a full screen tile menu. This was an attempt start a unified experience between PCs and mobile devices. The change worked fine on small screen devices but was a terrible experience on PCs. It was met with much outcry. The Start menu has returned in Windows 10 with something that kind of resembles the Start menu from Windows 7. It’s more of a combined Start menu — “Live Tile” experience. Live Tiles display updates like weather, news, and photos, while others are just a static application icon.

Adding to the confusion, there now two places where system settings reside: “Settings” and “Control Panel.” Settings typically run between devices like time zone, personalization, notifications, and user accounts. The Control Panel is mostly desktop specific settings.

Tracking: Microsoft Windows 10 tracks much of what you do and where you go. Their claim is they provided a free upgrade so you can give some information back to Microsoft on your usage. Two problems with this: even if you pay for the Windows 10 upgrade, this information is still shared with Microsoft. The other, this tracking is now rolled into Windows 7 and 8. Privacy advocates feel this is a violation of user’s privacy. The argument on the other side is most use Google or Apple’s services and they know just as much about you. This Ars Technica article explains tracking is a growing trend in technology: http://arstechnica.com/information-technology/2015/08/windows-10s-privacy-policy-is-the-new-normal/

Upgrade tips: create a full system backup using a backup service or create an image of your current installation on an external hard drive before attempting to upgrade. This is a backup incase the rollback fails. Check the vendor’s website of your hardware and critical software applications. Look for driver support or knowledge base articles about Windows 10 before upgrading. Knowing whether your devices and software are supported will help minimize regret because your favorite app or device no longer works.

Certainly some of these concerns have caused me to look at alternative operating systems. I have found in my deployments (I have yet to upgrade all of my desktops) with a little work, I can get 10 to act a lot like (my favorite) Windows 7. Turning off or uninstalling cruft helps a lot: turning off notifications, disabling camera & microphone usage, disable Cortana, remove many Universal Applications, and turn off background apps. I use Classic Shell to return a normal looking Start menu and Anti-Beacon to disable tracking. Links to those applications and ones to disable the upgrade nag-screens are below. Seriously, if you find any of these apps useful, consider donating to the author because we need to support those doing the right thing and allowing choice.

THE TECHNICAL COORDINATOR

Hey Gang,

It’s been a busy month for yours truly. Things got started off with a drive down to Columbus with my dad N8ETP. We visited the Columbus Radio Enthusiasts Society (CRES) on February 16th. It was touch-and-go for a while due to the weather. Snow hit both areas the night before and hoped it would hold off for the meeting. It did. We made it there and back, no problem. It was our first meeting in Columbus and we couldn’t have had a better time. I was contacted by Steve – N8WL to troubleshoot an RFI issue he was experiencing. We got to talking and he invited me to come down and speak about, well, myself –what the Technical Coordinator does and projects I’ve worked on. The presentation consisted of: my history in Ham Radio and how I got to where I am, laid out the ARRL and Field Services structures, section level positions and the Ohio Section, my responsibilities as Technical Coordinator, and projects I’ve worked on. In addition gave some pointers for troubleshooting RFI problems. Our Section Manager was on hand and helped answer specific questions about the section. It was an informative meeting. CRES: http://www.w8zpf.net/, presentation: http://www.k8jtk.org/2016/02/16/about-the-arrl-ohio-section-technical-coordinator/

The following weekend I presented at the Mansfield Hamfest during the Digital Forum. Danny – W8DLB, who is in charge of the Hamfest, was at my NBEMS training session in Medina County and asked me to present it during the Digital Forum. The Digital Forum covered voice and text based digital modes. Duane -K8MDA demonstrated FreeDV. FreeDV is a mode used on HF for voice communication. It’s impressive because the bandwidth is about one-third of sideband! I gave a portion of my training session on Narrow Band Emergency Messaging using Fldigi.

At the LEARA meeting in Cleveland, I showed the video for the Navassa Island K1N DXpedition which happened in February of last year. A DXpedition is an expedition to a remote location, usually uninhabited, for the purposes of activating the location and making as many contacts as possible. Navassa was my first time trying to chase a “most wanted” entity for my log. I was able to log them twice. Bob Allphin – K4UEE has participated in many DXpeditions and has released the story of many on DVD. I had no idea what it took to put on a DXpedition of that magnitude. After seeing his DVD on Navassa, I now have a better idea. It is a phenomenal video that got rave reviews and comments at the meeting. The main video runs about 45 minutes. The wrap-up from the Dayton forum is included which has some great background details. These are great for club meetings, introducing newcomers to Ham Radio, and gifts. Purchasing the video helps supports future DXpeditions and supports other hams: http://t-rexsoftware.com/k4uee/dvds.htm

Last, and certainly not least, Ken – KG8DN instructor at Gilmour Academy in Gates Mills, Ohio has been in charge of the Gilmour Academy Radio Club – ND8GA for as long as I’ve known him. During the school year, organizations are in charge of running Convocation for a week. This is a gathering of the entire school for announcements, happenings, events, and entertainment. Ken asked me to speak at Convocation one morning. This was a different type of presentation than I was expecting. I figured I would be there to talk-up Ham Radio and get kids interested. Nope. It was more about life experiences with a little Ham Radio sprinkled in. Things students could relate to. I have to be honest this was more challenging than I anticipated. A lot of time was spent searching for topics that students would care about, relate to, and how those experiences got me to where I am now. There was a visual portion which included many pictures from my high school years. When looking back on friends and people I shared those experiences with, it make me wish I was back in that time. I’m sure I’ll feel the same way when I look back on today. The presentation turned out great and I have to thank Ken for all of his help.

Thank you to everyone for coming to my various appearances and the organizers for asking me to speak with your organizations.

I received an email from a fellow Trustee of LEARA, Marv – W8AZO, asking if I had seen my name mentioned in a post on a website. I had not. What website did he find my name on? The IEEE website. Now, I know the fine folks over at IEEE (Institute of Electrical and Electronics Engineers) are wicked smart. Much smarter than I am. They come up with solutions to technical problems which usually turn into established standards. Additionally, they publish one-third of the world’s technical literature. Why the heck would they be talking about me? Stephen Cass – KB1WNR, Senior Editor for the IEEE Spectrum magazine wrote an article titled “Hands on: A Ham Radio for Makers.” He built an FM transceiver using an RS-UV3 transceiver board and Raspberry Pi to take advantage of digital modes. I was mentioned because Stephen used the instructions I posted to compile and run Fldigi on the Raspberry Pi. Super cool! I emailed Stephen and thanked him for the plug. He was very appreciative of the well written instructions. His article may have glossed over some important points relevant to hams but the goal of the article was to draw others in from the wider community. The article will be in the March printed edition of IEEE Spectrum and should be available by the time you read this. It hasn’t hit the shelves in my local bookstore yet. Online version: http://spectrum.ieee.org/geek-life/hands-on/hands-on-a-ham-radio-for-makers

That is what ham radio and makers are all about. I wanted to figure out how to run Fldigi on the Raspberry Pi, came up with a way to do it, documented it thoroughly, and shared it online. Stephen came across my instructions and used them as part of his project to create something greater; perpetuating the cycle.
