RADIO NOISE SUPRESSION

Postby GRAPEAPE94 » Sun Mar 06, 2011 9:55 pm



What is the best way to suppress the noise in my XM radio? A filter on the power line, a filter on the AUX lead to the radio or a combination of both? I get the engine noise when playing through the AUX on my system but not when using the FM transmitter built into the XM radio.

When I added a satellite radio to my goldwing, I had the same problem, I was told that it was due to a ground loop. I was sold an audio isolator (its a pair of small transformers that go between the audio output of the satellite radio and the audio input of the wing), it was a small box with a couple of 3.5mm plugs, I just plugged it in series with the satellite radio audio lead and the buzzing sound completely disappeared, I bought mine from eBay for less than $10.. Just make sure you get one with the correct plugs for your bike (or you will have to use a soldering iron to make the connections!!).

100% what Gary said...most auto/bike audio noise problems are due to ground loops. You can try bonding the grounds of the satellite radio and the bike's amplifier together with a big thick piece of wire - but you may or may not get rid of the problem, and as connections oxidize and fail, the noise will come back. A ground loop isolator will solve the problem permanently.

Thanks guys> Found a company called ELECTRICAL CONNECTION that offers a kit just for WINGS. It includes a power supply (convert from 12v to 5-6 volt) a ground loop isolator and a audio line driver so no volume is lost. It's pricey at $79.95 but if it does what they claim to me it would br worth it. Added plus, it's made in Tn.

Electrical connection also sells just a audio ground loop isolator that doesn't require power that will likely fix your issue...it's quite a bit cheaper than the one you mentioned, and they make it universal with headphone plugs, or wing specific with the plug that goes on the other end of your bike's aux cable...This alone will probably fix your problem:
