After 15 Year of posting about my passion for NASA and specifically the DSN, I'm finding it harder posting as an individual within the new NASA media framework. Its been a pleasure sharing my experiences and hopefully people have enjoyed them. All the best 😀

Looking for a Westbond ultrasonic module like the pictured. Sombebody knows where get one? My unit is damaged, I’ve purchased another but an error has ocurred in the shipping and I received a shampoo. If you have received this board I will send you the shampoo 😅😅 PSE retwit.

I have a bachelor's degree in engineering and am finishing a masters degree in space engineering. For telecommunication systems, I don't have formal training (except my master's thesis), but I have 5 years of experience developing SDR applications and working with SDR technology.

URGENT: I am looking for a university lab to take me in to do a PhD in the field of satellite engineering and/or radio communication systems. Since I'm not exactly rich, I would ideally like a scholarship. Please get in touch you have an opportunity (1/2)

What will amateur radio look like in 10 years? Amateur radio is changing, in the past we never heard about satellites, digimodes or SDR. Think out of the box and share your ideas in #HAMChallenge2024 iaru-r1.org/hamchallenge/202… #iaru_r1 #iaru #hamradio #hamr

Is very sad for me, post that Eddy ON7UN has passed to silent key. He was a inspiration for a lot of hams to start in moonbounce and microwaves. Rest in peace. #hamradio

SigDigger now supports history: if you suddenly see a transient signal but you were not analyzing that channel, worry not! Just hit replay, and the last N megabytes of samples will replay in loop mode until you figure it out.
