Here is my comments. Some radios are not fully remotable. That is to say, the face plate is remotable, but not the microphone cabling. This fact can and does cause problems with RFI.
Remoting also presents some additional power considerations. I have a lot of information on my web site about wiring, fusing, etc. Although pointed to the HF mobile crowd, it is applicable to VHF/UHF as well.
