this concept sound familiar, like decode ssdv image by replaying recorded .ogg audio file from multiple satnogs observations (in this comparasion satnogs network role as store and forward network) using direwolf as modem (ax25 decoder) (tnc serial framing), ssdv2sat or silversat.py to ordering the packet or fix broken data using reedsolomon/il2p (fixed using ssdv app) (in this comparasion role as LTP and Application bping, bpsendfile).
as direwolf support multiple modulation and baudrate, it support from AFSK1200 (like used by IO86 SSDV) to G3RUH 9600 baud (used by Silversat), RADIANT should support any modulation
