RE: Crazy wacky Electronics!
I must be lucky with both my cen sets (sabre) as I havnt had any problems with any of the cen radio gear. I also brought a cheap Mardave V12 to run about at work but i found the overhead cables caused a problem with that hence the change to 40Mhz ( I work at a power station so lots of interference about). You must be able to use a different freq to 27 though ???
