Installed a 40 channel Cobra WX ST Radio in

my truck, there is so much noise coming thru it
that its driving me nuts, Especially with the

A/C Blower motor on. I have tried to run it both
ways, thru the fuse box and directly to the

battery, Did not make a bit of difference.


1st clue.

Purchased a filter from radio shack and tried

that, no difference. I believe it is all antenna

interference, when I disconnect the antenna at
the back the noise drops about 80%.


It should go away completely if it's all antenna.

My question..... Am I experiencing a cheap

radio shack cable/antenna?


Possibly.

Would I have to run it outside the vehicle then

inside or would it be possible to shield the

cable with some type of aluminum foil help?

Appreciate any advise

Or interference from the electronic fuel pump. Google it and you'll find
the solution.
