It may be shameful but it is going to be the shape of things to come. Susceptible circuitry is rampant in a vehicle. Almost every electric motor in a vehicle is speed controlled by a pulse width modu

H EMC GUY, Hey, Ford should consider offering the option for better noise suppression. Most mobile rigs are costing over $1,000 bucks these days and on-board computer controllers can be equally expen

Of course. But there is no excuse for poor wiring practices, or for not bonding the body, for omitting ferrites at sensitive points in the circuit, or for designing those very complex systems with pi

I never buy new cars but would pay at least $100. for a service that implemented a genuine RFI quieting package to a used car. If I were to buy a $10,000+ new vehicle I'd hardly blink at adding $100.

The Crown Vics for police duty do have a number of differences in them for safety, convenience of mounting police accessories, and they are required to protect for radio reception in the radio bands

Mike, this is where I stopped with an attempt at an installation of a simple 2-meter 50w unit. What is "everything?" It'd seem that anywhere I'd route the power lead and the coax, they'd be next to

Yes. My Volvo S80 received NO RFI from my 100w HF rigs, and was moderately quiet with NO filtering at all by me. If I hadn't given it to my XYL's daughter, I would have dug in and cleaned some of the

What about the power leads from the radio to the battery? Are any particular routing precautions advised? As for the antenna, it'd be a quarter wave mag mount on the trunk - nothing fancy. Howard __

Don't give up. "Away" is relative, any separation is better than none, 4 inches of separation is a lot more than twice as good as 2 inches. Don't run cables and coax parallel to any automotive wiring
