[Elecraft] Data troubles

[Richard Ferch]

There is a narrow transmit AF filter configurable in AFSK A. If this filter
is turned on, you must keep your transmit audio frequency within the filter
bandpass, otherwise there will be nothing transmitted. Set your RTTY
software's audio frequency to match the K3's PITCH setting in AFSK A and
don't let it move around. You may need to disable AFC in the RTTY software,
and avoid the temptation to tune by clicking in the waterfall - use the
radio's tuning knob, the same as you would in FSK D.

TX works fine in DATA A
TX does not work other than trigering VOX in AFSK A.
