Field notes
The feature set is organized as individual radio apps: FM transceiver, APRS, RTTY, GPS, packet BBS, and TV test-pattern carrier, among others. The page describes RTTY reception from FM discriminator audio, with ITA2 decoding at 45.45 or 50 baud, and says the EXP menu currently includes ACARS, POCSAG, and SSTV that may change or fail to decode. A browser flasher is linked, and the page advises keeping a backup.
