Egads, who knew? Clearly not me. Of course, my K3 is relatively early,
and I didn't download the latest manual until this year. Thanks, Don!

Pete,
Go to the MIC SEL menu and tap 1 to toggle between the high gain mic
preamp and the low gain.
See page 52 of a more recent manual.

Don, I do not have a RPL bias option under Mic Sel. Only RPH, FPH
and Line IN

Set MIC SEL to RPL BIAS. You do not need the high gain amp with
that mic. It is likely producing feedback as you have it set.

Recently, I began trying to use the rear microphone jack on my K3
with my Yamaha boom mike, instead of using a stand-alone USB sound
card and feeding the signal to the LIN IN jack. This worked fine
for a couple of weeks, but today when I tried it, I got very loud
white noise driving my radio and amp essentially to full scale. I
have MIC SEL set to RPH BIAS, which has worked in the past. Any MIC
gain setting over 7 drives the amp to full output. When I pull the
mike plug out of the jack, the problem goes away.
