Hello Jim,
I tried the first part of your answer but my computer does not show similar
selections (Win XP) under sound/devices; nothing like you describe in the first
two paragraphs.
I have tried both VOX and PTT w/no success.
However, we may have hit on something here with the headphones in computer jack.
After hearing nothing with the microham CODEC selected for both Sound in/out, I
selected Creative Sound Blaster PCI for both input and output..aptly named, it
just about blasted out my ear drums... there was a 3rd choice presented in the
drop down menu which is: Microsoft Sound Mapper input/output.
Also interesting is that originally when selecting CODEC, it showed 02-mK CODEC
and 05-mk CODEC but after selected CSB then reverting to CODEC, it now numbers
them 01-mk CODEC and 04-mK CODECany significance to that?
Ok, so setup the JT65-HF for CSB in/out and on the mK II, selected CSB under
tab Audio MixerI get the tones when software sends, the rig is keyed, but
no power output.
While in this config, i.e., CSB on mK II, went to Audio Mixer tab and selected
'Test signal', I get the toneWhen I select mK CODEC on same tab...no tone
when selecting Test Signal ??? If I go to the K3 DATA A and change to AFSK,
then 'Test Signal', no tone. However if I select either FSK or PSK-D on the K3,
I get the appropriate 'Test Signal on the mK II.
So, I do not know why the CODEC is not producing tones for DATA A or AFSK...Joe?
Tnx again guys...this has me buffaloed...

What else do you recommend that I look for?
Look at the Windows PLAYBACK Mixer and see if the stereo Pan pot is
shifted to one side. When I use N1MM to run SO2R for a SSB or RTTY
contest, it moves the Pan pot to one side or the other to send my voice
messages to left or right radio. But it doesn't turn it back to the
center when it stops. This will happen every time you're using N1MM. I
suspect other contest loggers do the same. Also, either Windoze, or
other Windoze programs may be manipulating the Playback Mixer.
Playback Mixer LEVELS may also be the problem. JT65-HF, and other
digital software, uses the WAV input to the mixer, so look at its level,
and also at the MASTER level control. Neither should be all the way up
or all the way down, both should be something like 2/3 up.
The thing I'm puzzling about is that you say you're using VOX and it's
going into transmit, which means you're getting audio into the radio.
OR -- are you using BOTH VOX and PTT? Try VOX ONLY, and see if the
radio transmits. If it does, it's getting audio.
Another idea -- for a test, plug headphones into the computer headphone
jack and see if you hear the JT65 tones when the software is sending.
