Searching for info.

I'm a Amateur Radio Operator (HAM), and wanting to use Studio equipment for my station. The term used is ESSB, for Extended Single Side Band.
See ESSB Extended Single Sideband for a nice description of what we do.

I have the following equipment. GLX3000 mic, Event EMP-1 preamp, ART 341 EQ. One of the major issues I have is to ultimately remove spurious radio frequency energy (RF Noise) from entering my audio equipment. I ended up on this forum because I am trying to find a schematic for my microphone, so that I can determine where to put filter caps into the circuit, to cut the RF from entering into the system. I have installed many ferrite chokes around my station, and grounded everything to a common point but still the open mic is picking up enough RF that it is heard on my broadcasts. I have a very sensitive RF Probe I am using to sniff out problem areas, and the Mic is one of them.

If anyone can help me here that would be appreciated. I also am enjoying the read on mods around this GLX3000Mic and am wondering if these modes are worth the trouble or not.

Thanks all for your suggestions/help in advance.

Kevin
