[1000mp] Rtty not working on Mark V

Sun, 28 Sep 2003 12:10:46 -0500

To Phil and others:

In RTTY mode, when you key the MP by shorting RTTY jack pin 3 (PTT) to ground 
and touch pin 1 (FSK) to ground, the sound as heard in the monitor _should_ change 
in a mark to space transition.
That would be my indication of FSK working correctly.

Does _yours_ work this way?

Phil if you have an extra 4 pin DIN plug could you bring it to the meeting?
They are hard to find - meaning RS doesn't carry them <g>.

>> 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...
