Alan,
With the K3, you do not need a bias resistor at all. Just go to the
MENU MIC SEL and set it to aply bias - that is what the 'b' means.

Sometime back I bought a W2ENY electret conversion kit for my Astatic mic but I
seem to have lost the bias resistor/jumper that came with it and there’s no
value specified in the instructions.
I see that the bias resistor used with the Elecraft MH2 microphone is specified
as 5K6. As I want to
Thanks you very much Tom and Jim for the detailed responses. I have to
test my microphone for RFI. Jim, very interesting technical web page.
I have explained my easy to make microphone in my web page. Sorry, it is
only in spanish but the pictures speak for themselves.
Very interesting, Ramiro, I might give that a go.
Good to see that the ABS plastic box is clearly marked MADE IN
ENGLAND. Unfortunately we don't see that as much as we used to ;-(

Yes! I also was surprised by the made in England. That is a rare thing
nowadays. Now

Pin 7 and 8 are the same connection point.
The ONLY proper connection point for a cable shield is the shielding

as a pin 1 problem, whereby shield current (RF or
IF the cable shield is separate from both signal
conductors (that is,
hot and return, as in a balanced mic), it's fine to separate
return and
shield. But if there's only the shield, it MUST go to the
chassis.
If one ground pin was dedicated to the chassis or cabinet

Bob-
I use the SM-20 with my K3. Works fine!
I made an adapter cord for use with the K3 so I can still use the mic with
my IC-7000.
