Need your help - I hooked up my Starcom yesterday and I am getting way too much buzz when the engine is running. What can I do to fix the issue. Pulling power from a switched lead for my driving lights. Moved the ground to two different locations. Moved the unit around. Makes no difference. Thanks for your thoughts.

What else do you have connected to the Starcom? I had a similar problem but it was a ground loop on my radar detector and cell phone. Everything was fine until you started the bike.

First of all, the intercom should be grounded directly off of your battery. Or at least from a grounding strip that comes right off the battery. It is very important that as you add farkles, that ALL grounds come right off the battery. This is the best way to keep from creating ground loops in your system.

Also, what other audio devices do you have plugged into your StarCom that may be introducing a ground loop issue? Any device that is being powered from the bike's electrical system has an opportunity to introduce a ground loop issue, and therefore you'll hear the buzzing in your headset.

FWIW, I have my GPS, cell phone, iPod, FRS/GMRS radio, and Valentine One all powered from the bike and into my intercom system. And all without the lovely buzz that you're experiencing. But EVERY ONE of these devices has a GLI (ground loop isolator) cable between the device and my intercom system.

Two final notes: 1) I have not had any success cleaning up unwanted noise by cleaning up the power side of the equation. Removing the noise from the audio cables is the only thing that is "tried & true" for me. 2) I recently cleaned up some unwanted static from my Valentine One's audio be rerouting it's audio cable. Made a HUGE difference.

Hope this helps...

Problem Solved

Getting back to all of you. Thanks for the things to check. Guess what? An email from tech support at Starcom in the UK told me to pull power directly from the battery. I wired it tonight - buzz GONE. Will be riding to work tomorrow so I will give it a work out on the road...but the buzz is gone idling in the driveway. Guess power source matters. Jason
