[Elecraft] Using CM-500 with Elecraft Rigs

[Jim Rhodes]

Yes, what you said was " Kenwood, Yaesu and Ten-Tec transceivers do not
provide bias for an electret mic *at all*. To use an electret mic with
those transceivers one needs to install a "power adder"". Actually they do
provide bias to their own line of electret mics, so you could have been a
little more specific and said "for non-OEM mics".  We can't tell what you
are thinking when you type.
