[Elecraft] No output on K3

[Don Wilhelm]

Bruce,

Check the mic element in that ProSet - the type is normally printed 
where the microphone boom attaches to the headphones.
If it is an "iC" type, you need to turn bias on.

If there is a capacitor in series with the AF line in the MicroKeyer, 
then setting bias on in the K3 will not be effective because the 
capacitor will block the bias voltage.  Joe Subich can tell you about that.

It looks like Don had the right diagnosis—by turning the Windows and the MicroKeyer drive levels up to about 75%, and then restarting everything, I started getting power out on all digital modes. I then adjusted the MIC Gain as Don suggested and things are working well. THANKS!

Unless someone here has a similar setup and can advise me, I’ll just continue to work on it. I have the Mic connector from my Proset Plus headset plugged into the front Mic connector on the MicroKeyer, and the headset connector plugged into the back of the K3—which is what the MicroKeyer instructions seem to direct.
