Thanks everyone for all the offers for the bias box, I now have one OTW.
Jim, I was going to build one, it would certainly be simple enough. Try to
find a suitable battery box that will have room for the mic pass through
cables. I thank you for your always useful information.
So I figured plenty of people would still have them laying around on a K3
group. I lost mine I never had a use for during a move, or it's sitting in
my summer home in NJ.

Sort of near the end of this set of slides are simple instructions for
using ANY electret mic with any radio. You WILL need a soldering iron
and a few connectors. And you will need to open the manual for that
radio to find pin-out of the mic connector. Start with slide #168 and
continue from there.
