I use the CM-500 w/my Yaesu FT-897D as well as with my Kenwood TS-480SAT
with no "power adder", works fine.

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.

Read *ALL* of what I wrote. I indicated that the power is on pin 2
(Kenwood) or 5 (Yaesu/Ten-Tec) but one had to add a 5K6 Ohm resistor
and 1 uF blocking capacitor in order to use an electret mic. Those
manufacturers do not provide "automatic" operation with the CM500
or other electret mics.

NOT SO, DICK TRACY. All three manufacturers provide 5-10v bias
voltage on either Pin 2 or Pin 5, respectively - (and have done so for
many years.)
Elecraft did operators a HUGE FAVOR by switching bias voltage ON and
OFF with a MENU setting, adding an bonus measure of flexibility (...
which is NOT to be corn-fused with any sort of Flex-able Radio! ...
after all, this is CHAOS and we don't do that here ... ) ;-) Elecraft
earned bonus points for providing BOTH an 8-pin Foster jack AND a pair
of 3.5 mm TRS jacks to accommodate all sorts of microphones and headsets
without a middle-man adapter on its larger models - way ahead of the
field. / K8JHR /
