[1000mp] Rtty not working on Mark V

you may need to reverse the tones in the 1000 menu to get MRTTY to Tx =
correctly; I did.

Larry is asking about FSK for MMTTY - not AFSK for MMSSTV.

My 1000MP works fine with MMTTY FSK using the FSK pin on the 100MP's =
RTTY jack using a simple FSK circuit driven by my computers COM port =
similiar to what's shown on AA5AU's pages:

> 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...
