VHF radio noise

[Honeygirl]

I am getting bad noise from my bait pumps through my radios. I tried to stop it by rerouting the wires with no luck. any ideas. Joe

Live by the iron baby!


You would think they make an in line filter to suppress the noise.

Believe it or not I get static on certain channels from my GPS Screen.

Check your grounds. A bad or insufficient ground on the bait pumps or VHF could be the culprit.

As a test, put your bait pump on a stand alone battery. If the noise goes away, it's most likely the brushes in the bait pump are not making good contact with the commutator and that arcing is fed back onto your DC buss as noise.

If the pump is new it could take a few trips for the brushes to wear in, and if it's an old pump, break out another thousand (B.O.A.T.)

They do make noise filters that work pretty good. I think I got mine at Radio Shack or the local electronics store. They make them for the equipment that is causing the problem as well as the stuff that's being affected. I put them on the pumps and radios to cover all my potential problems.

Do you put it on the radio or on the pump?

10 or 15 years ago when I installed them, I put a filter similar to the picture above on the affected device (radio) and one on the pump that was made for the offending piece of equipment.
