Radio Interference

Hi Tom,

this is not my area of expertise.
But electrically noisy fuel injectors spring to mind.

cheers, Peter

My 100 series doesn't do that, but a previous common rail TD did (as you say .... on am, not fm). In my view, as suggested above, it's the electronic injector circuit - it cuts out when you take your foot off the gun (fuel not required). If you take your foot off while mobile, and slip into neutral you'll hear the noise die, but then come on again once the revs get down to idle. There should be a chair in radio inteference at one of the Uni's - bugger of a problem in modern cars.

Tom,

You didn't indicate whether the problem with AM reception was for all your trip to Qld, or only on the expressway?

The radios in Landcruisers have been Fujitsu for many years, and from my experience the AM section is as sensitive, or better than any other brand on the market. Upgrade with a Mobile One or Axis AM/FM whip improves reception markedly, especially in fringe areas.

There's parts of the Pacific H'way, either side of Grafton, where AM reception is worse than western Qld!!!

Looks like both Peter & Darian might have picked your problem, but has it only just started? Some road surfaces will influence AM reception in fringe areas, like bulldust, but wouldn't think bitumen would do it.

There's a couple of things you can do with co-ax & power leads that might help, if the problem won't stop.

Tell us how you get on,

Bob.
