Hi All,

I have a 4-pin desk microphone that came with an old radio, and I am 
wondering about the power input.
It is an RCA microphone, so it is a quality brand, but it came without its 
power cord.
I have tried finding information on-line about it, to find out what the 
voltage in would be, but have had no luck.
It works on a CB radio, but will probably work with any 4-pin input rig I 
get.
I had someone look at it and the only numbers that were on it looked more 
like a serial number, and not a model number, and did not help with my 
search.
Thanks for any information some of you might have.
