Whilst conducting a radio check, I had a friend comment that my transmission had a hum or buzz in the background -- voice came through fine. Any ideas on what might cause this? I'm wondering if some oxidized connectors might be the culpit.

Thanks, Max

First thing I'd do is get a radio check with another party to confirm the problem is on your side of the conversation.

"oxidized connectors might be the culpit"

Well, on general principles connections are always a good place to start looking... but dunno about them being a hum or buzz generator.

Is this noise something new? Do you have your radio cables routed near an inverter or other electronics? You might try turning everything else in the boat off and see if the noise persists.

Hi Max,

I agree that it might be corroded terminals or wires. More likely though you might be picking up interference from another electrical source. Did you have a battery charger on? Was the engine or outboard motor running? Was the depth finder on? Stereo?? Microwave oven?? Any of those can cause transmission "humm".
