Michael,
There is no one answer. Does your KX3 operate in voice modes when using
the microphone? If so, there is not a likely problem with the KX3.
Investigate your computer sound card levels to assure that you have
adequate audio levels going to the KX3. You should drive the ALC meter
on the KX3 to at least 4 bars with the 5th bar flickering. Those first 4
bars are to used as an indicator of the audio drive level.
Ignore the web advice for other transceivers which tell you to control
the power level with the audio input level - that will not work well
with the KX3. Adjust the audio (using the soundcard controls in the
computer and the KX3 mic level) to achieve 4 to 5 bars on the ALC meter
and adjust the power level using the power knob.
If you have questions about whether the computer soundcard is producing
audio, remove the cable from the KX3 mic input and plug it into one of
those audio amplifiers intended for use with iPOD or other devices -- do
you hear the PSK31 tones being sent. If not, look to your computer and
soundcard settings until you can control that audio output. Because the
computer/soundcard combinations can be so varied and computer/soundcard
related, no single answer can be provided. If you can give specific
computer and soundcard information, perhaps someone with a similar setup
can help you.
