Most hams are received in the LSB mode. Comercial statisons usually are
received in the USB mode or the reversed mark/space relationship. Also the
speed (baud rate) and shift are usually differant than the normal ham 45
baud (60 wpm) and 170 Hz shift.

I am using Ham Scope and Mmtty to decode RTTY with my sound card. It
works fine for hame radio operators but I have found RTTY on non-ham
frquencies and all I get is garbage. For example, there is an RTTY
signal at approximately 2.042 MHZ at 1100 UTC on the West Coast and
all that displays is random characters. I suspect it has something to
do with the protocol or baud rate settings. Anyone know what they
might be? Not sure if this is maritime station or not. Thanks.
