Static / Noise on VHF Radio

[mar3812]

Hello all,

I am doing a little experimenting and am having problems with static/ noise on my marine radio. As of right now the radio is mounted in my vehicle(hence the experiment). The noise/ static is pretty much constant, and adjusting the squelch has little effect. If the static does sop, it will return if I key the mic or if someone talks over the radio. It also seems to act up if I am around traffic lights and signals, gas station or bank signs, high power electric lines, and other miscellaneous wireless communication devices. I am not an expert by any means, but I do not believe that my antenna is bad because if I test the connection by pulling the cable connection in in out using the weather channels and it performs as it should.

The radio is a brad new uniden radio, could something be wrong with it? or is it indeed the antenna ?

How the eclectic or wireless communication devise effect the radio? what can I do to stop the constant static/ noise?

maybe install it in the boat where it goes and maybe it will go away

There's no telling what that noise may be, there are a lot of sources for it. I have to assume that it is probably ignition/fuel pump/etc. Would it be less if on a boat? Beats me, depends on the electrical systems and I know nothing about that.

Pulling on the ant. cable while receiving isn't a very good test of the connection. Is this also a marine antenna? The noise could be coming form lots of things. I would suspect your power wiring which should be connected directly to the battery. You might try some ferrite chokes on the power leads.
However, I don't see the point of curing the noise in your installation. I know it's illegal to transmit on marine frequencies from a motor vehicle, I'm not sure about having the radio mounted in one.
It belongs on a boat or perhaps at a marina.
