Thanks for your reply. Not that I really listen to the radio a lot, but when I DO, it would be nice if I could tune in something w/o static for some of my local stations. I guess it's just something we have to live with.

Just got an email back from Tony @ Iron Cross Audio also confirming the same thing...sigh of relief!!! I really didn't want to start dicking around with needless troubleshooting only to find out that that code is normal when having an amp in the mix.

Thanks guys....

Keep holding those buttons in until it displays DIAGNOTICS

cool. And then?

I'll be damned, it was right there beween the handlebar sticky and how to pick up your bike if you drop it sticky. Can't imagine why I missed it. lol.

But serious though, thanks for the reference. It's a gem.

It's probably RF noise being generated by the pulse width modulated (PWM) power supply in the amp. I'll bet if you sniffed that thing with an RF field strength meter you'd peg it.

You might want to try putting some clamp-on ferrite chokes on the power leads as well as the inputs and speaker outputs of the amp. They're available from Radio Shack, part number 273-105 for the larger wires (you can do both positive and ground power leads in a single choke if they'll fit through it), and 273-069 for smaller wires. It would be OK to run 2 channels worth of the input and speaker wires through 1 choke if you have enough wire. Doesn't matter which part number choke you use. Just pick whatever size choke you can fit around the wires.

The chokes need to be located as close to the amp as possible.

If that doesn't solve it, then the noise is being radiated directly from the amp chassis into the radio or to the radio's antenna.
