Hmm, tried a couple of programs and I tried RTTY but there were so many baud rates etc... that even if it was clear it was damn near like encryption just trying to hit the right combo.
How do you know what shift, bits and stop whatever (1, 1.5 or 2) ?
I have another at 2.520 right now I'm listening to. I am using Digtial Master under the HRD program menu.
