Martin,
Please check the "PITCH" setting vs. the mark tone generated by
your AFSK software. The K3/K3S contains a very narrow audio
filter on the input audio (CONFIG:AFSK TX). If the AFSK TX
filter is ON and your software does not match the K3 PITCH you
will see the behavior you describe.
73,
Sorry. But DATA A is for USB modes like FT8, PSK, etc. RTTY (FSK) is a LSB mode
and should use the Sub-Band AFSK A on a K3.

NO! RTTY is LSB, and requires AFSK A. DATA A is USB, and is used for all
other computer-generated digital modes.

Well done Richard. Gold star!
SYNC DT.
Don't ask, I have no idea. MMTTY demod was set correct, I use 915Hz but
the TX audio was different, like 2125Hz.
Panic over hihi!

So far as I am aware software shouldn't be changing. No CAT connection
from rig to PC, just changing mode on the front panel of the K3 and
sending tone in the LINE IN connector.

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

Check the DATA Sub-mode. You may be thinking AFSK but the software may reset to
FSK D and that doesn’t require audio into the sound system.
In the TX monitor, Do you hear diddles or just a single tone?

I can set DATA A and then send audio from the PC into the radio. It
transmits fine, no problem. Just switching to data mode AFSK and then
sending audio. the vox operates as
