So I got my allocation for IPs in the 44.* network space. Next question, what to do with them? I've looked at JNOS which looks interesting. For those of you who have amateur network IP allocations, what are you using them for?

Two of our local radio clubs have started holding Health and Welfare nets (one nightly) to provide a forum for local information during the COVID-19 event. Speaking only for myself I have found this meet up comforting and would recommend it to most clubs but be careful to ensure that you have a calm, scientifically literate, and well informed member run it!

Getting fldigi connected to my baofeng under Ubuntu was as easy as plugging in my new SignaLink (with the correct jumper settings), firing up pulseaudio and selecting the new sound card for playback and record.

Captured this image from today using a Baofeng BF-F8HP with Nagoya NA-771 antenna, decoded in real time using android app holding phone close to radio with app running.

On the topic of automatic tuners, I think understanding why you might need one and more importantly why you might not is key. This video makes it pretty clear I think.

Gary, KD2PYB announces APRS and SSTV High Altitude Balloon Event planned for those within 500 miles of Binghamton, NY June 29. More details at

Test of running solar this weekend. Definitely not ultra-portable, but good for operating near a vehicle. Tripod stand gets the base of the Comet GP-3 to 4 meters, 35Ah AGM battery, Renogy 150W panel and controller, Kenwood TM-V71A (2m/70cm).

You'll know you've been practicing CW enough when you start hearing Chickadees calling "2 2 2"

Found a CW beacon on 2 meters near me. FLdigi mostly decoded it, but got some of it wrong - perhaps because it was keyed by hand? In any case it was fun to discover it!

Got the old Vibroplex keyer making some sounds with a raspberry pi (actually a pi-top which has a speaker) and some python.

Got it hooked up to a pi-top with a little python program to make a 800Hz tone. Getting it set up has been a challenge, but at least I've got it making some sounds now!

...and everything with add-ons is resolved as of this morning. Turned out to be an expired cert.

egads. Suddenly all Firefox Add-Ons have been disabled in the browser across all platforms everywhere. Wonder if it is related to this work:

Building this circuit might be a fun project so I can start to play with that old Vibroplex. I think I have all these parts just laying around anyway!

My mom gave me her old key this weekend. Needs a little cleanup and to be set up properly. Looks like it was made during WWII (~1943).

I'm still practicing CW every day for almost a month now. I'm on lesson 31 of 40 at and have been practicing with character speed between 15 and 17 wpm and effective speed between 3 and 7 wpm.

OH8STN makes great radio related videos. I enjoyed this one which details his portable digital field comms station with raspberry pi.

Congratulations to Katie Bouman to whom we owe the first photograph of a black hole ever. Not seeing her name circulate nearly enough in the press.

Amazing work. And here’s to more women in science (getting their credit and being remembered in history) 💥🔥☄️
