Despite some generous help, I'm not doing well setting
levels for
transmit from my FT-817. I am using a SignaLink interface
and am
following the suggestions that came with it.
When I set gMFSK to Transmit/Tune, I hear a tone. Although
neither my
Master volume nor PCM volume are muted, increasing the
playback levels
should turn on the SignaLink PTT LED, but that never
happens. Reception is fine.
I can't use their test for the soundcard because my card
does not
support full-duplex. Also, gMFSK says it does not support
full duplex
in/out.
What I'd like to ask about here are my gMFSK preferences.
Under Devices, Sound,
Sound card device: /dev/dsp
Requested sample rate: 8000 (default)
Tx rate offset (ppm): 0 (default)
Rx rate offset (ppm): 0
I checked 8-bit sound in/out, and left stereo and full
duplex
unchecked.
Under Devices, PTT, for device I use /dev/ttyS0, and for PTT
line
(serial), I have both RTS and DTR checked. I leave unchecked
the Use
inverted PTT logic.
Part of my problem is that I have little or no idea how to
make these
choices.
