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 expensive. I think Ford might be
surprised just how many radio operators would be willing to spend
another $50 or $100 bucks to ensure a relatively noise free and safe ride!
I've got the noise reduced so much in my Sport Trac I can hear the noise
from the anti-lock brake sensors on my AM radio, haha.
73,
