Question Noise Interferance

I get quite a bit of interferance through my headset from the engine and specifically the brake hydraulic motors.

Clearly, the sollution is to fit a capacitor across the power supply... Does anyone have any experience with this? i.e. What size cap. to use?

Smile interference

You don't mention if you are using a GPS with your setup but if you are, you need a ground isolater audio cable to hook the GPS into the sound system. My K12S with a mixer, radar detector and satelite radio work fine until I plug the GPS in then I hear all of the noise you mention, the isolater was the solution.
Both MIXITPRODUCTS.COM and ACCESSORYWORKSHOP.COM here in the states sell the needed cable. Hope this helps

Cool no GPS link

Nope, not using any GPS... the interferance is there when only using the rider-pillion intercom... thus must be comming through the power source... I think it's the same kind of problem that old car radio's used to have, which was solved by inserting a capacitor between the terminals of the battery

Just go down to radio shack and get one of thier small car stereo power line filtiers.
3 wires, 5 minutes and you don't have to worry about screwing up some electronic gizmo with a 1930's shade tree fix.

Noise Interferance

I also had a noise interference problem with my Autocom unit when first installed. I would get a "wine" which would increse with engine speed. My autocom unit was located under the seat in the area of the tool box on a K1200GT. I resolved the problem in a very inexpensive manner. I took some alluminum foil and placed in between two paper towells and them wrapped the autocom unit with this and secured it with tape. I then connected a wire to the alluminum and grounded it to the frame - no more noise problem.
