You might be surprised. In my setup I can switch back and forth instantly between FSK and AFSK. I have done some testing with a second receiver, and my K3's RTTY signal seems to be cleaner in AFSK than FSK (lower odd-order sidebands). My guess is that this is due to keying transients in FSK. I assume the AFSK from MMTTY uses some form of waveform shaping or phase-coherent transitions between the two tones, resulting in lower keying transients. 73, Rich VE3KI ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
