I'm using RTTY with my K4 using AFSK, the Xcvr Frequency display (at the top of the WinWarbler window) matches the radio and commander, however the waterfall frequency display is off by the 2125 mark offset.  It shows 7078 (aprox) when the radio shows 7082.  What do I have setup wrong.

I would use FSK, but this is a remote setup and I have no way to do FSK, just AFSK.

Thanks,

Assuming the K4 is similar to the K3 in this respect, when it is in AFSK A mode the dial displays the mark frequency, not the suppressed carrier frequency as it would in SSB or DATA A mode. In that case, you need to set the Mark Offset in WinWarbler to -2125, the same as you would for FSK. See <http://www.dxlabsuite.com/dxlabwiki/K3PSKRTTY>.

Rich,

   thanks!  I will check that out later today.  Yes it's the same as the K3, or supposed to be.  I have never run my K3 AFSK, always FSK.
