[RFI] Suggestions for an RFI-clean battery charger/maintainer

[Jim Brown]

I'd bet that anything like these will be noisy pigs. Two solutions, 
depending on your resources. 1) a linear supply like we would use in our 
ham station with a suitable charge regulator, like one of the West 
Mountain Radio PowerGate units. 2) a left over power supply for a 
Thinkpad with a Genasun charge regulator. Thinkpad supplies are pretty 
quiet, and you can add a ferrite choke on the AC cable as a backup. 
Select the Genasun model for lead acid.

He will be mostly using it for charging his RAM truck, which has 2 truck batteries in parallel all winter (big diesel).  Also would be good to use it for charging other dead batteries around the house...
