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.

All,

I have my KX3 connected to a computer and am running FLdigi.  For psk31, I
set the KX3 to VOX, and the mode to DATA-A.  When I send characters from the
FLdigi, I see no bars in the ALC display.  What could be wrong?
