Minimal Hardware IP over VHF/UHF Radio using RpiTx and RTLSDR. Currently sends test frames from a Pi to a x86 laptop with a RTLSDR V3 (M1). Currently building up an integrated rtl_sdr/fsk_demod receiver appplication (M2). The "Pirate radio RasPi" project can probably be used instead.
DIRE WOLF (Decoded Information from Radio Emissions for Windows Or Linux Fans) is a new software implementation of the APRS protocol. Rather than using a hardware TNC, this software implementation lets you plug the soundcard jacks into your radio to work APRS. The page could stand to be better organized, but you'll find pre-compiled binaries and source code at the Download tab.
