[RTTY] MMTTY difficulties

[Jim W7RY]

My guess is that either you have an RF problem or your serial port is no 
working properly. I have had issues long ago trying to send CW with a serial 
port. It started out fine but as it went along, the characters started to be 
random and not making sense.

What are you using for a serial port?

Yes I'm using a NPN transistor for FSK on DB9-3 and another NPN on DB9-7 for 
keying.
