Interference

Can anyone advise on why i get bad interference on my Standard Horizon GX1500 when the engine is switched off but when engine is running it disappears?

Could understand if the other way around.

Cheers

When you say interference do you mean white noise or is it a buzzing/whining sound?

Mate, sorry for the lack of description but it is the noise you get until you adjust the squelch. Turn the squelch all the way and still get it....strange?

Cheers

That is a strange one, if it got worse when your motor was running but the other way around?
Have you done a radio check with the engine on and off?
Think you'll have to wait for more experienced folk than me for the answer mate

could it be (and this is a guess) that with the engine off you have poor power/connection to the radio and with it on you get better voltage to the radio - either its being supplied by a different route, or more likely there is corrosion on a connection meaning that you get <12V from the battery but >12V when the engine is pushing our 14V ?

You beat me to it, though I'm guessing too.
