[Elecraft] AFSK

[Larry K1UO]

I'm unable to transmit an AFSK signal in DATA mode, although I can transmit
via the same LINE IN
in DATA A mode.  The line output from my SignaLink USB soundcard does have
the audio signal on it and is connected to the Line In mono jack on the K3. 
For MIC SEL in configuration, I have Line In selected.  DATA MD is set to
AFSK A and shows 45 bps.  PITCH is set to 915-170.  Using MMTTY software and
the latest K3 firmware the K3 goes into transmit mode (audio signal is
present on cable feeding K3's Line In) but no modulation.  What am I
missing??

I should mention this was working as early as 3 weeks ago and I have NO idea
what has changed.    Just reloaded the K3 firmware and checked all MTTY
option parameters but all look good and as I mentioned..Data A xmits the
RTTY signals but not AFSK.
