Hi Eddie,

Yes, i can try. However i have no idea if it will be "better". Not an
expert on the subject.
What i like is such a fast mode like RTTY, maybe 40 Baud would be fine
as well, but not much slower and no limited number of characters. I like
the function to just write down and the program sends it immediately :-)
So if there is another mode that has some error correction, it would be
an improvement i think. And AMTOR has it, if i understood correctly.
So what the hell is MFSK-4? Yes, Multi-Frequency-Shift-Keying with 4
tones, fine. But what does it offer? We can just try but i would like to
understand at least basically what i'm doing.

I will now switch to MFSK-4, same QRG.

73, Stefan

Eddie, Gary, Chris, Minto, MF,

I've read a bit about RTTY and AMTOR in Wikipedia. Maybe AMTOR would help us a bit more, even when not used in that ARQ mode but also in beacon stile, due to the FEC?

MultiPSK has AMTOR with FEC, yes we don't want ARQ do we. I have run it, same width as RTTY the FEC may help but its just as fast it is QSO mode.

Again I will ask the question, why is MFSK not being considered I am running it at the moment on 478.200. MFSK4 is on Fldigi can you try it now.?

Eddie, what was the name of the program that offers that mode for free? I cannot find your recent email where you already mentioned it.
