      • Notes vs P4dragon de Demetre M/SV1UY
      • 1) The P4dragon supports RPR, like the Tracker does!
      • 2) The P4dragon does NOT support AFSK 300baud HF PACKET, like the Tracker does!
      • 3) The P4dragon supports 1200 and 9600 VHF PACKET RADIO, the Tracker does 300/1200/2400/9600 & 19200 PACKET RADIO.
      • 4) P4dragon can work APRS as a standalone APRS Tracker and DIGI, like the Tracker does!
      • 5) P4dragon cannot operate in Toggle APRS mode. Tracker can do toggle APRS mode (i.e. operate as an APRS Transmit only Tracker in both RPR (centered at 1500Hz) and 300 baud AFSK PACKET (500Hz higher), sending an RPR BEACON first, and almost immediately after it, a 300 baud AFSK PACKET BEACON. Of course in TOGGLE MODE, the Tracker cannot receive, but it's DCD sensor is still listening, so it does not transmit on top of another station. It is not act as a BLIND TX ONLY TRACKER and it does not cause any collisions!
        • Another thing that no other HF PACKET modem can do in 300baud HF PACKET MODE, but the Tracker can do, is to be +/-400Hz frequency tolerant and when it has to reply to a 300baud HF PACKET signal that it is transmitting in the wrong frequency within the +/-400Hz, it can QSY to the wrong frequency only to reply to the station that is in the wrong frequency! Then it's transmission frequency reverts back to the right frequency!
