Hey gang,

Despite the severe weather briefings for August 5th in northern Ohio showing a slight risk of severe storms throughout the area, didn’t have storms near me. The August 6th briefing was shaping up about the same. Though there was a chance of tornadoes, it was under 10%.

On an otherwise bright, sunny, and warm day, I left work ordering food to be picked up 30 minutes later on the way home. As I was driving home, with the windows open, on I-90 to the west side of Cleveland, a tornado warning had been issued. As I approached my exit, a stark contrast to the current sunny conditions, I was facing a blackened sky looking west. “Oh, this isn’t going to be good” I thought. Hoping it was far enough away that I could pick up my pizza and make it home before the storm hit.

After getting off at my exit, still a half-mile away from the pizza shop, I was stopped at the intersection of Hilliard and Canterbury near my house. The wall of rain hit just about 3:52pm. Hurrying to pick up my food, quickly running in an out, I was drenched. In the 3, to maybe 5, minutes I was on Hilliard, picked up my pizza, and made it back to that same intersection, a large tree had come down across Hilliard Blvd.

Tree down on Hilliard Blvd at Canterbury Road (Westlake, Ohio – taken 8/9/24)

Not only was there debris from trees and branches being blown around all over the place, trash and trash buckets were being blown around too as some residents had already put their trash out to the curb in anticipation of pickup the next day. I made it safely home as I only had to travel a block and a half. The intense part of the storm blew through in less than 15 minutes. Staying in my car, the worst had yet to be discovered. As I made my way from the car into the house, I discovered many large tree branches had come down in my backyard.

My wire HF antenna was about 100 feet long strung between two trees across the backyard. I figured it was a goner. Maybe the branches were far enough in the back of the yard that it somehow missed it. Even if it was brought down, wouldn’t be the first storm where I’ve had to replace my antenna. I didn’t get lucky twice in one storm. Without going to survey the damage just yet, I could see pieces of wire dangling so I knew it was not in one piece anymore.

A little while later going out to look, the fence post used to connect the coax feedline to the antenna feed point was snapped off at ground level, brought down by a tree branch coming off a neighbor’s tree. Landing perfectly on the post like those branches were placed there. Don’t know if my antenna was ripped down by the fence post being destroyed or from being in-path of a large tree branch flung across the yard, which would have been no match for a wire antenna. Between trees in my yard and the neighbors, there were 4 to 6 large branches sheared off from the upper parts of 70′ trees.

Luckily, no damage to any other property and no one was injured or worse. Damage to my HF antenna and setup is extensive. The post would need to be dug up and replaced, the entire run of coax from the shack replaced, and a portion of the PVC housing needs to be replaced. There was also some electrical in a separate run out to the post. Dad (SK) and I worked to install all of this about a decade ago over a summer. To make matters worse, I may lose my antenna supports as at least one tree is severely damaged and need to be assessed.

In my completely amateur observation, seems like straight line winds, if nothing else. There weren’t any branches twisted off trees so I don’t think it was a tornado. In the coming days, many in the area had trees removed and debris cleared.

My street had power throughout but the opposite side of the block was without until the weekend. By night time, it was obvious many did not have power because there was a hum of generators running in the distance. That area lost power due to the tree that fell where I was minutes earlier and other significant damage not far away.

Reports released by the National Weather Service office in Cleveland on the August 6, 2024 storms show one tornado dissipating a half-mile from my house. Would it have kept going, it would have passed over my house and probably a contributing factor to the damage in my yard, others on the street, and damage seen on Hilliard. A second tornado kept along the shoreline but came within a mile and a half of the QTH. There is a quite impressive video from a beach cam in Vermilion showing the approaching storm and fury as it makes landfall.

The shack itself was not damaged by the storm, though it has been on my to-do list to replace. Not sure when I’ll be able to rebuild but will be off the air indefinitely.

As posted on the ARRL website and highlighted in my June article, the ARRL fell victim to a ransomware attack in May. It was revealed the payout was a $1 million ransom. Well, not so much the ARRL but their insurance paid out. Initial asking was a multi-million-dollar ransom. Since the ransom holders did not have access to any significant compromising data, it was reduced to $1 mill.

It has been stated the ARRL does not collect any data that’s not already public (largely data the FCC has on file for our licenses) information on its members, we’re not at risk in this compromise. However, the article notes, employees of the ARRL may have had their private data leaked (such as social security numbers) in records kept as part of employment.

For all the benefits pitched to get companies ‘moving to the cloud’ and using ‘AI,’ not the least of which include user credential protection – knowing when bad guys are attempting to gain access using employee credentials to compromise systems – and malware protection for cloud services and endpoints. It is good knowing those protections stopped and prevented the spread of malware. Wait, what… the ARRL’s cloud systems were compromised too? Well, that worked out well. These features are smoke and mirrors and provide little to no actual protection.

DSCF5081 K8JTKHey gang,

DMR: you’re hearing a ton about it from the Ohio Section and the number of repeaters has exploded with nearly 60 in the state. DMR saw growth due to inexpensive offerings of quality radios at last year’s show. I suspect this year will be no different with new offerings from vendors, possibility of dual band radios around the corner, and many more groups supporting DMR.

How many of you know the terminology and could program a DMR radio from scratch? Passing around a code plug makes the mode seem plug-and-play and it’s a great way to get started. Relying on existing code plugs leaves most of us unable to change the configuration of our own radios or even know how it works. What happens if you need to change programming, add a repeater, the code plug information is old, or wrong?

When I started last year, I found there was very little information available on DMR in ham radio. I learned DMR by doing a couple things. First, I looked at the code plug I downloaded for my TYT MD-380. I got a lot of knowledge playing around with that. There were a couple things I wasn’t quite sure about. When I got together with a buddy who was interested in DMR, we further played around with the software, tried different settings, and I filled in those gaps.

With the continued support from the Ohio Section, one of our Technical Specialists, Dave – KD8TWG has been giving training presentations on radio programming and he created a DMR Learning Series explaining terminology and etiquette: https://kd8twg.net/category/dmr/dmr-learning-series/.

I put together a paper with the goal of explaining DMR to the person just starting out and include some more technical descriptions. It started as an idea to write an article or two for the OSJ around Dayton time so anyone jumping in would have good information. After starting the project, it quickly became much bigger.

The first writing talks about the DMR standard and compares it to other made-for-ham-radio modes like D-STAR and Fusion. One topic that might be of interest is the section on ‘is it legal?’ I’ve heard this question come up frequently and even clubs in the section are questioning the legality. Radios, CPS, code plugs, registering for a DMR ID are all discussed. I talk about repeaters, c-Bridges, networks, and some of the issues one might encounter. Terminology covered includes time slots, talk groups, reflectors, contacts, RX Group Lists, channels, zones, scan lists, and hotspots: http://www.k8jtk.org/2017/05/10/dmr-in-amateur-radio-terminology/.

The second will deal with creating a sample code plug for a factitious repeater, tying all the terminology together. Afterwards, you will be able to create and update your own code plugs! Stay tuned to next month. DMR repeaters in Ohio: https://www.repeaterbook.com/repeaters/feature_search.php?state_id=39&type=DMR.

At the request of Cuyahoga County Skywarn, Technical Specialist Dave – KD8TWG has installed a Sage EAS ENDEC device on the 146.76 repeater in Cleveland. 146.76 is the primary Skywarn repeater for Cuyahoga County. The device is the same used by radio and television stations to broadcast Emergency Alert System messages. It monitors NOAA weather radio frequencies and broadcasts tornado watches/warnings, thunderstorm watches/warnings – for Cuyahoga County, and the weekly EAS test. It’s been performing flawlessly!

The data and attention tones are the same everyone is familiar with. These are the same one would hear tuning to a broadcast radio or TV station during an event. In order to not clobber an existing QSO, the device will delay playing the alert until the repeater is free. DTMF tones are available to Skywarn NCS’s to disable the alerts if it begins to interfere with the net. Some innovative working being done here. Thanks for the hard work Dave.

Anthony – K8ZT, our ASM for Educational Outreach, shared some links with me from his site. He has put together lists of great resources for doing projects, ideas for the class room, training classes, and build projects a group my want to coordinate:

After my write up of podcasts last May (http://www.k8jtk.org/2016/05/15/ohio-section-journal-the-technical-coordinator-may-2016-edition/), I try to catch ones that feature a ham in the Ohio section. QSO Today episode 144 featured John Ackermann – N8UR. John was a past president of TAPR (which I’m a member) and is a big proponent of open source hardware and software (openly sharing designs that make the community better). Eric and John talked about his usage of SDR radios and this collection of test equipment. He’s done alot of experimenting with APRS and shares some of his lessons learned. I especially liked his idea that hams can achieve much greater data transfer speeds in the 3 GHz portion of our spectrum. Maybe others in the section will develop technology to utilize that spectrum more than we are currently. The podcast is available on your favorite podcast app by searching for “QSO Today” or by going to: http://www.qsotoday.com/podcasts/n8ur.

Don’t forget #HamNation300 special event is starting the Wednesday following Dayton. There will be stations operating D-STAR, DMR, Echolink, possibly Fusion, P25 and anything else we can get our hands on – in addition to SSB. I will be doing D-STAR, JT65, and maybe PSK too for some HF digital contacts. Points challenge is available for those who enjoy the social aspect of a special event. Tune in to Ham Nation (twit.tv/hn) every Wednesday evening. Details can be found on our event page: https://www.hamnationdstar.net/2017/04/05/ham-nation-300-special-event/. I will also be participating in the Ham Nation forum at Hamvention on Saturday, 10:30a in Room 1.

The show featured the digital net controllers this past Wednesday (5/10). My ugly mug was featured along with my good friend Andrew- WA8LIV from the DMR net and Dave – N3NTV from the Echolink net. You can watch the segment if you dare: https://youtu.be/afWX5kQSBAg?t=1h11m27s or download it at: https://twit.tv/shows/ham-nation/episodes/299. There’s a reason (more than one?) I stayed behind the camera when I worked TV production. I kid, check it out and join in the fun of #HamNation300.

That’s about it for this month. I’m looking forward to meeting all of you at Dayton (er, Xenia) this year. I’ve heard there were a record number of ticket pre-orders which I hope means a successful year for Hamvention. One thing I can guarantee for this year: it will be different for all of us. I’m excited to see what’s in store at this new venue. Get your shopping lists ready…. and see you at Dayton! Thanks for reading and 73… de Jeff – K8JTK

DSCF5081 K8JTKHey 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 dv4miniand 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!

DSCF5081 K8JTKHey 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 DMR Logo 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. Tytera MD-380 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 WSJT-X Conversation 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 Yaesu DR-2Xrepeater 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/.

Raspberry Pi 3I 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/.
