[Elecraft] K3s rear mic connector and shure SM58.

[Joe Subich, W4TV]

Mic bias is used only with electret microphones.  Dynamic (moving coil)
microphones like the SM58 can be damaged by DC on the coil!  The bias
will certainly *further reduce* the output from the already low output
of the dynamic mic.
