I couldn’t resist putting together a simple fact sheet for my portable 10GHz EME station, as I’m so satisfied with its performance 📡 A real pleasure to operate whenever I get some free time for battery-powered moonbounce 🪫🌓 #hamradio #amateurradio #hamr #10GHz

Amazing Corona at the public solar eclipse event in Palencia, Northern Spain. Has been a real great experience.

The total solar eclipse in Northern Spain will be amazing tomorrow. NASA will be live streaming from a fully rented village nearby. High density of Astrophysicists and Tourists around here in a normally not touristic part of Spain. I am in the center of totality trajectory. :-)

NASA will stream the eclipse starting at 1:15 p.m. EDT (19:15 Spain) from Villalibado, a nearly empty village in the province of Castile and León. Over 30 scientists are setting up cameras to study the eclipse and stream the celestial event in real time nasa.gov/live

Spent last few days coding. Autonomous M5Stack Core. A work in progress. Watching over groundstation vital signs. Faux LCD green display … a nod to displays of yesteryear. Nokia 3310. Ethernet link to operating position PC/SDR Console. #qo100 #hamradio #amateuradio #amsat

Less and less interesting Inmarsat stuff at the Hamradio flea market in Friedriechshafen. Found this nice Thrane&Thrane Inmarsat-C antenna. I have the same already in my collection :-)

NEW FT8 AUTO-LOGGING!!! While HAMRS and World Radio League were crashing, Hamtrax added wireless FT8 decoding. No special cables. No software. Just phone + radio

Interesting project. Part of it can also be done without external hardware out of the box with wfweb by @k1fm by connecting to your IC705 without internet in local WiFi AP mode. Maybe cool idea to add DXcluster functionality and some web based logging to wfweb, too? :-)

Tried wfweb by @k1fm on my iPhone while on the road. Nice to see the responsive web layout adapting for the phone browser. Frequency tuning a bit tricky by swiping the waterfall (lower spectrum bandwidth helps). All in all very cool to work my station from a phone. 😊

Some idiot, self-styled, "OSINT" vibe coder has been DDoSing kiwisdr.com and individual public Kiwi's with continuous floods of kiwirecorder connections. I've blocked them on kiwisdr.com. I hope to have a fix soon for individual Kiwi's. 🤬

Please stop this or switch to the WB part of the transponder. Thank you

@amsatdlApr 9
#AMSAT #QO100 Unfortunately some people are starting to using the NB transponder for LORA transmissions, which exceed the 2.7kHz bandwidth. See below with different spreading factors. This is a violation of the NB transponder bandplan, please move to the WB transponder!

Just for old-time sake, 30 min of Artemis-II S-Band in the 1-meter dish! DSN-Goldstone utilizing 2 (larger) dishes for today's 2Mb/sec comm session. Amazed to see ANY signal from less than 20° EL here in dense forest!
