The latest firmware revision to the NinoTNC has PSK shaped transmit envelopes 2400 Hz wide and up to 2400 baud!
// 3/4.31: 24-Oct-23 :
// : Improved DCD LED coast time and CSMA logic.
// : Added IL2P+CRC (IL2Pc) modes to reduce false decodes.
// : Restored full dynamic range of AGC.
// : Change self-learn callsign algorithm to UI frames only.
