[Elecraft] K3 RTTY Decode Not Woirking

[Jim Brown]

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?
