Thoughts About Birds
Satellites, that is. This post is a follow up to my LEO Learning Curve post from earlier this month. I think of this as sharing some notes, providing context, and trying to make them readable for others. One thing you can’t rush is experience. You can prepare, study, make notes, organize information, and so on,…

2022 News Flash – Yaesu FT-818ND Discontinued
As 2022 draws to a close the amateur radio community was in a bit of shock as Yaesu announced that production of the FT-818ND will cease as well as the FTM-400XDE. Greater minds than mine have paid homage to a classic: K4SWL at QRPer.com OH8STN recounts his feelings here A thread on the SOTA.uk board…

LEO Learning Curve
Note: I got caught by COVID and am isolating, so now I’m getting caught up on blogging. Also focusing on keeping my wife safe and healthy while I get through this. It sux. No fun. I’m off the sats for a while while I recover. On with the blog. Recap: My setup is a Yaesu…

Full Duplex Satellite, It’s in the Bag – Part 1
Opening Salvo directed at amateur radio transceiver manufacturers: The lack of affordable full-duplex all-mode radios is why I have to write this. You would think the shack in a box (SIAB) market segment would have at least one or two full-duplex-capable radios. You would be wrong. Buying new? You can buy the Icom IC-9700 VHF/UHF…

Satellite Communications and the Void
I often call Amateur Radio “the void” because it is an almost bottomless pursuit. I’ve been licensed for 30 years now and was lucky enough to fall in with an active ham radio club in Farmington, Connecticut, the Insurance City Repeater Club. They met at the Red Cross offices near UCONN Medical and that meant…

The Well Tuned Eggbeater
I’m taking some initial steps toward working satellites this fall, and part of that crossed paths with dialing in my APRS setup, which led to me working the ISS digipeater with my homebrew copper cactus. While that worked, I was having deep fades and dropouts due to the vertical polarization of the J-Pole being incompatible…

Catching Radio Waves
Most hams go through cycles of days or weeks or months where they operate more intensely or take a more relaxed approach. Those “lulls” might look like doing more listening, or working on projects, or making cables, or any of the maintenance things that need to get done. In my current situation I am balancing…

Shortwave Listening for Robots
When I was a kid my grandfather gave me a Hallicrafters S38-C, starting me down the road to radio madness. I had already been listening to AM Broadcast DX, though all I knew was I could hear the Red Sox games from other cities, like Chicago and Kansas City, late at night with my AM…

Lightweight Antenna Roundup 2 – Chameleon MPAS Lite v Wolf River Coils SB1000 TIA
When I was running mobile HF in the 1990’s and early 2000’s I accumulated a bunch of 3/8-24 mount antennas. There were hamsticks, Hustler coil-loaded whips, an Outbacker Perth, plain whips… Outbacker sold a metal tripod that was marketed as a ground plane and antenna mount in one. I didn’t spring for that. I just…

The Resonance
The reason why I would bother with this topic is twofold: One: I think better antenna systems are actually better; and Two: Technical concepts are central to amateur radio and should be understood and employed as often as possible. I’m discussing these antenna concepts in simple terms in the interest of keeping it accessible. Hopefully…
