Read more "Satellite POTA demos March 26th"In 2013 I posted on the Ten-Tec mailing list about a problem with this 6 meter transceiver kit I built when I was a new ham, in 1998. Within a few years, the final died. I replaced it, and it died again. I didn’t get it figured out in 2013, but recently Bob Cady, W7JNM […]

Read more "Check out my DJ mix at QSO Today Virtual Ham Expo"Since January 17th, AMSAT has been troubleshooting a “low or no signal situation” with the recently launched RadFxSat-2/Fox1-E satellite. Since January 28th, ARISS has been dealing with a separate issue with their radio system failing to downlink after an EVA (space walk) rerouted their ARISS antenna cable. In my opinion, the way ARISS has communicated […]
Read more "Comparison of AMSAT and ARISS official statements about respective anomalies"While the space station was brightly lit and high overhead Durham, North Carolina last night, I did an ISS ham demo for my friends’ kid who is really into space now. He is on the autism spectrum and has memorized the gravitational forces of most of the planets in our solar system. It’s really amazing. […]
