The Radio Shack electret elements can be used to make a very effective (and
cheap) microphone. I've used them a number of times, as have many others.
Perhaps you did get a bad one, but that's easy enough to verify by simply
trying another one--they only cost a couple of bucks. One thing though, you
need to house the element in a proper way. I don't know how you are doing
it, but hopefully you are mounting the element is a good microphone housing
of some sort.
However, I'm confused by your wiring description. You should only need to
make one connection to pin 1--the microphone lead. The K3 applies the bias
based on the internal settings you make through the menu.

Subject: Re: [Elecraft] Microphone question - K3
I tried a RS electret element I have here and the audio is distorted and
weak
- do I have a bad element or am I doing something wrong? I wired the
element directly to the mic wires bypassing the transformer in the mic
with
no cap or resistor. The red wire and audio to pin 1 and the ground to pin
7. Guess I'm clueless when it comes to electret mics!
