With a Yaesu VX-5 powered from a Radio Shack car cord attached to the
console cigar lighter socket, I get rapidly repeating noise likened by
others to spark plug noise; but, no spark plugs on a diesel. Removing
the card cord and transmitting on battery eliminates the problem.

I'm about to switch from the VX-5 HT to a Kenwood TM-V7A; how may I
avoid this problem when installing the mobile transceiver.


Thank you in advance for your on-topic suggestions.
