I'm all for anything that keeps me from fiddling with the K2's filter setup! The thought of playing with them makes me squeamish.
I just downloaded MMTTY and installed it on my computer at the office and now see where I can change the mark freq to 1275 Hz. I know I should be embarassed for asking this, but: If I'm generating tones at 1275 and 170 Hz shift and somebody who's software is set up for 2125 & 170 Hz tunes me in, he'll centre me in his display and decode me fine. But if he transmits with his setup won't I have to re-tune to decode him properly? Ohhh...I know I'm going to regret this, but it's Monday and I'm not firing on all cylinders yet! 73, Ken Alexander, VE3HLS --- Don Wilhelm <[EMAIL PROTECTED]> wrote: > Dohn, > > You can always tune the PSK31 signal with the K2 VFO > so the audio will > appear near 2210 Hz rather than the more traditional > 1000 Hz.
