John:
Go top page 49 [Menu Functions] of the manual (rev c). Read what it says
in the Main Menu Table under MIC SEL entry.

Hi I have sn 709 - I have my Heil HC4 from my TS-2000 8 pin conn - when I
plug it into the K3 - I hear noise from the MICROPHONE???
The 'manual' says: " to select front or rear panel microphone AND to turn
BIAS on/off, use the MAIN:Mic SRC menu entry..
My firmware 1.78 only shows: MIC SEL FP.H b1 A5 and I have not figured
out how to adjust it - the main VFO knob also gives me a choice of rP.H and
LInE In ..
On a separate note - I have this anomaly that I emailed support on Friday
night:
"Managed to 'lock-up' my K3 - NO buttons work - including power - had to
pull the power plug....
going thru the config menu - at PTT-KEY both ' OFF-OFF' tried to change
values and complete lockup
Completely repeatable - go to config PTT then move main vfo control and
lock up.
Was on AM 13840 listening to a SW station/
Changed mode/freq - still does it - as soon as main VFO adjusted. "
Any advice/help comments?

This is a known problem with the Rev B front panel artwork. I had the
exact same problem with a MH2 mike when I first used my K3/100 SN 729 a
week ago on 6 meters to contact a local friend who is a well-known VHF and
HF DXer and contester. Unfortunately it did not make a good impression!
There is a ground trace missing from one end of C98 and C97 on the front
panel board. These capacitors are associated with the mike bias circuit.
Hence the problem with the MH2. I am told that an official Elecraft fix
is going to be released this coming week. Several of us who noticed this
problem were given the fix to try and it worked three out of three times.
If you must use a mike that needs bias then use the rear panel connector
for now (i.e. Elecraft or Icom Proset). MH2s are excluded of course,
unless you have an appropriate adapter. 688 is the earliest SN that we
know is affected. The other three were 690, 728 and 729. Elecraft is
fixing front panel boards now before they ship anymore.
