A colleague showed me this awesome website where you can connect to people's SDR (Software Defined Radio), tune to some frequency, and listen to the broadcast. If you are, like me, interested in amateur radio and radio transmissions in general but don't have the equipment, check this out: https://rx-tx.info/ If checked the map at https://rx-tx.info/map-sdr-points to find a nearby station. #amateurradio #hamradio #sdr

@finn yes, this is a good site to start listening HF, it's a first step to get hamradio license. 73 Riccardo IU3QOA

@finn https://www.receiverbook.de/ is another nice overview page. I did an introduction on SDR the other day, where OpenWebRX+ is one of the 2 softwares I'm introducing. Slides: https://fluxcoil.net/files/presentations/20260124_tlug_sdr_introduction.pdf The slides also have a link to the recording.

@finn @df4or Maybe have a look if this is down your alley, too. It’s a website with some Information about the number stations. It also has all them listed and a the link on top brings you to a pre-tuned SDR for the next broadcast :) https://priyom.org/number-stations/station-schedule

@finn at the risk of swamping them, my three favorite sites with really good antennas, low noise levels, and multiple sdrs are: https://k1vl.com/sdr.html - maine, USA https://blackcatsystems.com/kiwi.html - maryland, USA http://websdr.ewi.utwente.nl:8901/ - Netherlands
