[RFI] WHINE on XMIT using IC2100

[WA3GIN]

Hi Folks,

 

A local ham buddy here is having a hell of a time trying to rid his 2m
audio xmit signal of whine from his alternator.

 

He purchased a used crown Victoria from the police dept. Here are the
actions he has taken to resolve the RFI:

 

-          installed new alternator

-          ran a ground from the alternator to the neg terminal of the
battery

-          ran a ground from the neg terminal of the battery to the
engine block

-          grounded the radio

-          ran power cable directly to the battery

 

I would have thought that the measures he took above would have solved
his problem.

 

Ideas are welcome.

 

73,
