[RTTY] Help with keeping RF out of PC

[Marco Spalluzzi]

Hi Peter, if it's an rf related problem going into the pc, you can put some
little isolation transformers on the soundcard in and out wires, to isolate
it from radio.
Note that if you use fsk, you need just the "in", so less wires used, less
probability that something can go wrong...
In the N1MM's site, in the interface section, it's recommended to do like
this also for that reason.
Also, try to simulate a transmission, or really transmit into a dummy load
with 0 power, so you can understand if it's rf causing that, or a sort of
conflict between mmtty (under n1mm) and the operating system.
