Dick, You did not tell us what RTTY Software you are
using??
If you are using MMTTY, there is a setting for AFSK,
or FSK, also FSK with sound. I would check that
first.
2nd if you are using Writelog with MMTTY, then there
is a setting called LSB is really FSK. That is used
for AFSK. It has to be checked to work.
Since his cable works on your machine, then I would
think that the program that is creating the RTTY Tones
has a setting wrong.
