[OZAPRS] Bad HF noises in Landcruiser ??

[Tim Ahpee]

Hi Geoff,

There was an article in AR back in September 2007 where VK3XP and
VK2DKN used some ferrite clamps around the cable coming out ofd the
injector control box.

The article didn't say what the noises sounded like but if it is
injector related then it is going to be engine speed releated. 

Cheers,
Tim
