This is the most difficult article I’ve ever had to write, not only because I lost a very good friend, but also because it’s so hard for me to put into words and express the impact this person had on my life and others.

I met Rob about 25 years ago. Rob lived in Philly working long hours programming minicomputers. He developed various medical issues and had to retire early, relocating to the Poconos here in Pennsylvania. He tended to be a night owl, sleeping all day and relentlessly pursuing amateur radio projects at night. We served at our struggling local ham radio club for several years, me as president, him as vice president. He joked his callsign should be VP4LIFE. Rob was a ever-present friendly voice on the local 2 meter repeater, welcoming beginners and having conversations with other night owls well into the morning. We spent many a night at Field Day, operating the CW station and we both substantially improved our CW skills over the years.

Rob and I tended to be mentors to each other. We frequently had multi-week email conversations going about projects. Rob would get interested in a topic and he’d call or email me. Rob always seemed to know the right questions to ask. I would research the topic and inevitably get interested in it. We went down many technical rabbit holes over the years, some going nowhere, others resulting in some sort of rig, circuit, or antenna. I would often wake up in the morning to one or several 10,000+ word emails with pictures showing what Rob was experimenting with. Rob never bought a few components for a project, he’d buy 1,000 of each, and stockpile the unused parts in case he wanted to build more of something or give the parts away to others. Our last major conversation was about making vacuum tubes from scratch, with him collecting the necessary tooling and materials to do this. We complemented each other well, with Rob having the energy, curiosity, and ability to create the spark, and me with the technical know-how to figure things out and fan the spark to become a fire. I can honestly say I am a better radio amateur and person today because of Rob.

I’m still in shock over the loss of Rob. I often see some neat project and think that I should email Rob, but realize he’s no longer around. I open in my email in morning expecting to read a long diatribe about some late night experiments, but there is nothing there.

Radio Skinny-Dipping

I have been working on a homebrew 40 meter CW transceiver for over a year now. It’s a superhet design, with all discrete components built ugly style on copper clad board. I’ve taken various circuit designs I’ve built in the past and added some new ones. The project has been a great opportunity for me to use and learn about the NanoVNA. Every stage I built, tested, and tweaked with the NanoVNA, and recorded results in my lab notebook. The rig features a 4 Mhz IF, mainly due to me having a ton of these crystals. I built wide and narrow filters, just futzing around with various crystal and capacitor combinations, and implemented diode switching of the filters. The filters aren’t commercial grade, but they’re definitely good enough. The final PA uses an IRF510. I had to do several iterations of this before I got something to work. At 12 volts I get 4 or 5 watts, but I normally run it at 24 volts to get 10 watts. I’ve had it up to 36 volts, outputting 20 watts. I’ve been wanting to try 48 volts.

For the longest time the rig was just PC boards on my bench interconnected with alligator clips, but a few months ago I made it a bit more respectable and mounted the PC boards on a pine board and completed some permanent wiring. There are still several alligator clips jumpering things to make it work. I tend to leave the rig on all the time and just listen to it in the background while doing other things in my office/lab/shack. I even leave it on when I’m experimenting with or adding a new circuit, if possible.

I’ve made several contacts here and there when I stumbled upon someone calling CQ for POTA, a contest, or SKCC. I honestly haven’t been doing any logging or any paper code copying. There’s something satisfying about just walking over to the rig, tapping the alligator clip-connected straight key, and having a quick contact. There’s no keyboard, no waterfall, and nothing to navigate with a mouse. It’s just me and a bunch of components communicating over the ether.

Conflict of Interest

The ARRL Ethics and Elections Committee has recused a director for publishing a book that competes with ARRL publications, creating a conflict of interest. I find this strange as ARRL is a non-profit amateur radio advocacy organization, not a for-profit company driven by shareholders’ financial interests. I thought, perhaps naively, the goals of ARRL publications were to promote and enable the hobby, and not primarily be a line of business or product offering that competes in the marketplace.

I find the framing of this really troubling, with the “ongoing conflict of interest” being caused “through the creation and publication of a book which competes with one or more ARRL publications”. If the book was published in the public domain and available for free, it still would compete with ARRL publications, and arguably would still be considered an ethics violation, despite such publication being totally altruistic and compatible with ARRL’s mission of amateur radio advancement. Such competition could perhaps also be claimed for publishing a website of antenna designs, or volunteering for a non-ARRL VE organization.

There is a conflict of interest here, however it’s ARRL’s interest in publication offerings that is in conflict with its primary mission of advancing amateur radio.

History

Found in my grandfather’s ham radio stash….

A History and Critique of Field Day Logos

My favorite amateur radio event of the year, by far, is Field Day. Each year ARRL issues a new Field Day logo. Let’s take a look at logos of years past.

First, let’s get the mediocre ones out of the way.

The 1980’s called. They want their logo back.
The 2006 logo was meh. Get ready for more radio waves.
The 2019 logo wasn’t awful, but it was rather unremarkable and low effort. At least replace the yellow with something else. Is that a target or radio waves?

I think the 2015 logo was made with Microsoft Word on someone’s lunch break, another low effort logo. Hey, where’s the ARRL diamond/antenna circuit logo? This is the only logo in the bunch where the ARRL diamond took a hiatus. All you’re getting this year is some radio waves.
The 2018 logo had me scratching my head. The design is actually good in my opinion and took some work, but what is up with Grid Chase and #hashtag #hashtag? This one just feels really contrived and like a commercial or a promotion of some program.
I’m sorry, but the 2022 logo, well, it’s blah. It feels stiff and uncompelling. Why is the ARRL logo wearing headphones? I think an engineer attempted to be a graphic artist. No, just, no.

Now let’s look at some good logos.

2007 and 2013 had cute cartoon logos. Not bad.

2005 and 2014 were yagi antenna years.

I actually like the stylized yagi in the 2014 logo, and On the Air from Anywhere is a rather clever. But what is up with the yellow?

Radio waves are a common theme, as seen in the 2006, 2015, 2019, 2010, and 2022 logos. In 2008 we had Ride the Waves, but with a sine wave representation. (Hey, why are there two of us transmitting on the same frequency?) This logo is nice. It is visually appealing, free-flowing, yet more sophisticated than a lot of the logos. But ditch the yellow. Please.

The 2021 logo isn’t too shabby, though I feel it could have used some refinement. This is the only logo in the group depicting modulation. Looks like AM to me.

I can tell a lot of effort went into the 2011 logo. It’s the only logo of this style, and is quite different from other years. I get the feeling I’m in Arizona or New Mexico. Yellow is OK here. We’re in the desert. Hey, why aren’t we on top of that mountain? Man, it’s hot out here. I need a cold drink.

2016 and 2017 had monochrome style designs. I like both of these as they have a simple, yet cool feeling. 2017 was another yagi year, though we got stacked yagis as a bonus. Are those more radio waves, and emanating from a boot? In any case, I give FD16 an A+ for the outdoorsy color choice and the hiking boot footprint. Well done.

2009 is hands-down my favorite logo, however, I won’t declare it the best logo. Hang tight. This logo has it all. I adore the forest green color. I love the font choice (the same logo was used in 2005). We have a person and their dog. (Who doesn’t love a friendly dog?) You have evergreens, and an old school wall tent for camping. You got a yagi and a dipole. Is that the sun or the moon? Don’t know, don’t care. This logo illustrates the perfect FD setup for me.

2012, in my opinion, is another great logo, though I may be biased due to its theme being similar to the 2009 logo. Note that the 2014 logo has a similar yagi. I like this stylized depiction of a FD site. Good job.

And now for the best logo, evar…

The 2020 logo is like no other. It’s cool, it’s hip. (Perhaps even chill ?) Someone at HQ thought out of the box and nailed it. You got an old VW bus, ARRL logo stealthily yet stylishly placed on the front of the vehicle (and not plastered clumsily on the side like other year’s logos), whip on the side. Business in the front, party in the back. As if that wasn’t enough, we got your radio waves and a groovy font. Can we get more of this in coming years?

I Lost My Logbook and I Feel Fine

Late last year I applied an operating system update to my Macbook and my solid state hard drive peed all over itself. Long story short, I was unable to boot from the drive or read it and I had to start all over with a different hard drive and a fresh OS installation. I was able to recover all my files from the cloud except a recent backup of my logbook. It appears backups of my logbook, which MacLogger DX apparently stored in a hidden directory not in the Documents folder, was not being backed up to the cloud. The last logbook backup I can locate is from 2015.

But honestly, I don’t care. I’m declaring logbook bankruptcy and starting over. I already have some plaques on the wall for DXCC and WAS. I’m not in any race or competition. I’m not contributing any more to the radio art if I’ve made 10,000 QSOs rather than 500.

It’s a new day, and a fresh new logbook. It’s rather refreshing.
