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.


Okay, I have some questions about RTTY:

1. What unencrypted RTTY traffic is out there besides hams?

2. What sort of encoder would I need to read RTTY with my NRD-525
and what do I need to know to get it functioning?

3. My receiver has an RTTY mode. What exactly does that do in my
receiver? Couldn't I just use USB or LSB?

Thanks,

Greg


there used to be press services on RTTY.
