[Elecraft] K3: TT-700 Mic with higher K3 bias?

[Joel R. Hallas]

I'm thinking of packing the K3 for vacation and realized it wouldn't hurt to
have a mic along. I don't want to lug a desk mic, and I have a drawer full
of various electret models. One that is currently surplus is a Ten Tec 700.
The only possible issue I see is that the Ten Tec Paragon I used it with
supplied 4 V while the K3 provides 9. 

I don't seem to have the TT mic docs any more, so not sure what the
acceptable bias range is. If it won't work directly, I can use an internal 9
V battery. If I knew if the battery went to the same place that the radio
bias went, I'd be done <g>!

Does anyone know whether these will play together?

Thanks much!
