[1000mp] Rtty not working on Mark V

Sun, 28 Sep 2003 7:57:25 -0500

Larry,  The MMSSTV program generates audio tones for RTTY. It is AFSK (audio frequency shift keying) and does not shift the carrier frequency (Frequency Shift Keying).  Therefore you must use the MIC input (or the Phone Patch input) as the input on the transceiver. With MMSSTV you operate in LSB mode and the MMSSTV program generates the tones. Good luck...
