Hi Guys, and the Gals.
I am picking up engine interferrnce through my GME 4200 UHF CB on Ch5.
It's picking up the revs of the engine and when i accelerate, this is emulated through the GME speaker.
This causes hassle as i can't scan - the bloody thing keeps locking onto the engine!
I was told to go and buy a EMI block thingy.
As the car i have is a Mitsubishi magna '95 V6 3.0ltr, do i need to buy 6 'EMI thingys' one on each plug lead, or do i need one EMI thingy for somewhere else, or attach it to the GME somewhere?
I'm using a RF Ind 6db anntenna.
Is there any specification that i need when buying a EMI thingy - they look just like a ferrite core thing - for different cable thickness's upto 10mm.
Any help would be appreciated.
Thanks,
Alan.

I don't think you need a specific type ????
I'm not a radio guru, but I've had the same trouble you had, and I fixed it by re-routing the antenna cable (the coax).,
I've had similar troubles with AM band on the car radio, and found that the EMI 'slugs' didn't help!
I have a number of electronics devices...cameras, etc... and some have EMI cores fitted to the cables(from the manufacturer), where the cable passes through the core and then wound around to come back through the core again!
Don't know if that's the way it supposed to be done????
