[RTTY] FT-920 & RTTY

[k0bx at arrl.net]

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.
