[ARC5] adventures in battery ops

[mstangelo at comcast.net]

I didn't follow the original thread but if is operating from an auto 12 volt battery an upconvetrer is an option.

If you are talking about a standalone option I'd use a 24 volt battery or two 12 volt batteries in series.

I did the second option may years ago when I had a "portable" conmmand set receiver.

There is, of course, another way to deal with the 12 V- only issue: there are 
on eBay and other places "up-converters" which accept a 12 V input and 
output 24 V.

To my way of thinking, if/when I want to use our favorite radios in a 12 V 
system, modifying the filament string for parallel operation is the least 
intrusive and very easily reversed simple way to deal with the problem.
