Using CM-500 with Elecraft Rigs

Elecraft earned bonus points for providing BOTH an 8-pin Foster jack AND

headsets without a middle-man adapter on its larger models - way ahead
of the field. / K8JHR /

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.

Re: Using CM-500 with Elecraft Rigs

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.

Re: Using CM-500 with Elecraft Rigs

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