For those "Space Antenna" fans, here is the link to the 1963 paper on the Telstar1 Satellite antennas, which was written ~8 months before I was on the planet! It includes my new favorite VHF antenna and the 4GHz and 6GHz transponder antennas. #hamradio articles.adsabs.harvard.edu/cgi-bin/nph-ia…

I saw a Twitter post on the Telstar1 satellite from 1962. And now I must have a copy of the VHF antenna that was on the top of it. #hamradio

Installed a new battery in a friend’s laptop and needed to run the battery 🪫 to zero for calibration. So I ran several of my favorite #HamRadio YouTubers in parallel to load up the CPU / power consumption. The combined audio was pretty hilarious. Who is the Dummy Load now?

Please make sure your antenna doesn’t forget which way to point once it gets up. #hamradio

Sometimes you just need a little help to keep the nearby 5kW AM Broadcast station out of your homebrew RF frontend. #hamradio BTW: Marki Microwave has a rather nice on-line RF filter design tool if you need one. markimicrowave.com/technical-reso…

I rather enjoy the sweep analysis capability in AE6TY's SIMnec program. It allows you to easily see the impact of component tolerances circuit performance. In this case a High Pass filter to kill AM Broadcast. Just be sure to put the frequency sweep at the top of the list.

Not that useful when you’re trying to decode CW at speed, but an interesting graphic nonetheless. #hamradio #CW

Laser cut a clear Lexan case for the P3ST transceiver project. After all the soldering and assembly work, the only option was a see through case. A big “shout-out” to Aagaard Moto Foundry for letting me use their Glowforge laser cutter. #hamradio

If I ever start a business to sell ham radio antennas, I will have to fight the urge to name it something like Piggly Wiggly. #hamradio

I T’S ALIVE❤️! After a marathon point to point coax wiring and soldering session the #P3ST transceiver has passed the smoke test and is receiving signals. Plenty of debugging yet to go, but it finally looks and sounds like a real SSB radio. #hamradio #hamr
