[RTTY] TX problem

[Dick White]

I spent some time in the SARTG and Rookie contests this past weekend. I was
running 90 watts ( don't have amp) and an external cooling fan. During the
SARTG contest rig would stop transmitting. By turning it off for a few
minutes I could TX again. I thought my cooling fan may have stopped running
and the heat protection was working. The time I could TX kept getting
shorter until now I can not TX at all. The radio can TX CW and SSB. I have
tried to TX RTTY in MMTTY, N1MM and MixW programs. It apparently is a
software condition. I did not change any of my set up. This just suddenly
started. I have looked into my settings and I don't see anything out of
order. I am set up for RTTY only, no CAT or any type of rig control or
spotting used. Just plain RTTY to run contests thru N1MM with the MMTTY
engine.

Any suggestions as to where I should look for the problem is appreciated.
