I have been testing CATS.radio protocol today, setting up SDR-iGate and flashing RS41ng. Promising results!

Good reason to go pick some RS41 radiosondes, free CATS.radio transmitter inside :)

Figured it's finally time to activate this account (and not post to that other service only), so the best way to start is with some #amateurradio hacking:

This #Graw DFM-17 #radiosonde has learned some new tricks and it chirps CW (morse) and Horus 4FSK modulations on the 70cm ham radio band. This is a work-in-progress port of my #RS41ng radiosonde firmware, as the DFM hardware is very similar to #Vaisala #RS41.

Next up is #APRS + testing, so soon you'll be able to repurpose your #DFM17 sondes!
