Pin 6 is dc voltage but unused. No capacitor in mic. How does this thing work? Excuse my ignorance, but dynamic mics have always been my thing. Electrets are new to me.

Wouldn't it need a capacitor to keep dc voltage out of the radio?
It seems as if a circuit like this would be necessary, but it doesn't exist.
The radio should power the mic element via the audio pin. If you were to install a dynamic mic on such a radio you should use a blocking cap if the mic doesn't have one.
Any idea how to wire this thing? I wanted to temporarily put the electret inside this case until I got a noise cancelling one. Plug is wired exactly the same as the stock AT-6666 mic.
Now I got 4 wires and am not sure what to do with them. Dynamic mics are a breeze, but I'm new to electrets and I would hate to mess something up.

Not just by looking at it. Observe the polarity on the mic element and check the voltage before you install the element. If it were in front of me and I had a schematic or just time to trace wiring I could give you a better answer.
stick with the mic the radio came with. Its about as good as it gets for that radio.
A stock CRE microphone sounds better and a stock President mic sounds even better than that, so I had no intention of using the Stock
AT-6666 mic except as a parts donor.
I have cre and president lincoln 2 and mag one mics and all sounded much the same with my voice...Like everything..horses for courses!
I just realized I have cases of these and was wondering if anyone might know how to rewire the EV602 and keep the audio amplifier and wire it to the AT-6666.
You were right. 5 volts on audio wire.
You were right. Thanks for the info.It is in the radin main PCB.
Just take DMM and measure.

I haven't tried this but it might be of interest to you if you're experimenting with different elements.

That was the point of putting that element in that case. Now that I know how to wire it, I can experiment with other elements. Looks cool. Has a leaf switch and solid case and cord. Sounds great and cost $3 to make.
