Finally Got The Darn Cb To Work

Some of you may recall my incessant wining over the past year about the lousy BMW CB radio on my '05LT. The problem that I was fighting was a loud squeal in the receiving radio every time I would transmit. I tried with no success; rerouting wires, additional grounding, a variety of commercial and home built filters, and just about everything that anyone suggested. In my previous post on this subject I said that I had finally given up and was going to abandon the project. Well being frugal, my wife says cheep, I decided to try one more time. For no particular reason I took the radio that I had just removed from the bike and hooked it up crudely and simply used some test leads with alligator clips connected to the battery for the 12V power. Amazing! it worked just fine. So, one more time I stripped the bike down and reinstalled the radio except that rather than hooking the 12V power source to the fancy BMW supplied power supply/filter I connected to my 6 circuit Blue Sea fuse block. This is a power source connected directly to the battery through a simple automotive electro-mechanical relay that turns on and off with the ignition key. The results are astounding. It works just great. Apparently the noise was being generated by the BMW power source that is switched on and off by a 12V output from the AM/FM/Intercom when it's turned on and off. Don't know if this "fix" will help any of the rest of you out there that have been fighting a similar problem but I thought I'd let you know what finally worked for me.

Thumbs up Congrats!

This is why I always suggest running all of your farkles off of a fuse block (and grounding strip) that comes directly off the battery. Unless it's heated gear...that should come directly from the battery itself. Glad you're all good-to-go Lynn.

And for the record, I don't think you're "cheap" at all. "Frugal" is a much better word for you.

I know the man. "Cheep" works just fine
