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 Am 06.03.2013 16:33, schrieb g3zjo: > Hi Stefan > > On 06/03/2013 15:09, Stefan Schäfer wrote: >> Eddie, Gary, Chris, Minto, MF, >> >> I've read a bit about RTTY and AMTOR in Wikipedia.
