Apparently I don't understand the use of DTR/RTS for PTT.
If I assert DTR, the red xmit LED comes on, but when I send an RTTY
string to the rig, there is no output. DTR is turned on in CONFIG. I'm
in DATA mode and set for AFSK A. What I'm after is a way to avoid VOX
with CW ( Yeah I know for
Mike,
You are apparently setting PTT with the DTR signal OK,
But, how are you sending a RTTY string? If you are using AFSK A, the
RTTY string must come into the K3 as audio (likely from a soundcard) -
the easiest is to use the K3 LINE IN - plug a stereo cable between the
soundcard line out
