Re: [Elecraft] 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. 73 de Jose Douglas KB1TCD On 11/8/2020 10:03 PM, Jim Rhodes wrote: Yes, what you said was " Kenwood, Yaesu and Ten-Tec transceivers do not provide bias for an electret mic *at all*.

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.
