[Elecraft] K3 RTTY Decode Not Working

[Jim McDonald]

Jim,

I'd never used 915 Hz before, as I'd been using 1275 for quite a while now
with the K3.  I left MMTTY alone and just turned the K3 pitch to 915 and the
TEXT DEC to thr 3 and ON with FSK D.  The K3 is copying now on 20 RTTY just
fine.

I tuned in the signal first at 1275 with the crossed ellipses in MMTTY
before I switched the radio to 915.  I have three bars on each side with
CWT.  I'm using a 300 Hz DSP BW with the 400 Hz filter now.

I'm actually using DXLab's WinWarbler with MMTTY, but I think that's
irrelevant.

I've got two K3s in an SO2R setup. RTTY decode does not work with either 
one. It's turned on, I'm using the lowest tone set (915 Hz), set for 170 
Hz shift. Plenty of signal, CWT is on and centered. MMTTY decodes very 
well. Decoder simply dumps out random characters.  I've played with the 
threshold settings, and with AF and RF gain settings. Tried AFSK A and 
FSK D, no difference in decode.

Any ideas?
