Re: Codar AT5 TX
I think the electret approach is a good idea, they also seem to work well with transmitters that use carbon mikes. I know of several people who have built them and used the original carbon mic DC supply to run a small amplifier.
In the shack I have a box of 15 to 20 unused mic inserts that I was told were crystal types. They are quite small, about the same diameter as a £2 coin. I shall see if I can test them out on my AT5.
