Circuit to take electret mic. to carbon mic. input.

Also uploaded to "Files".

There is a method to this which will be obvious as I progress.

This will be quite helpful elsewhere. I have a bunch of small mobile hand
mics that I want to use for a variety of projects. Being able to connect
them in place of carbon or dynamic mics is a good thing. The downside is
that they're small enough that putting batteries inside would be difficult
at best.

I am using a NOS 1974 Motorola desk mic with a built-in amp that runs on the 5VDC provided by my BC-375E for its carbon mic. Literally "plug-n-play". Folks in the west Coast Mil-radio net Saturday nights (3993kHz at 2100 PST) like it. Came with a manual and schematic that I'll add to the archive if there's interest (and some-one will do some hand-holding as I've never done that yet.
