Re: System Voltage

[JOHN PITTELLI <jplily-at-yahoo.com>]

Eirk, You'll find that you can never have enough
batteries, we each currently carry 2 12 volts to each
battle. Do you think you can locate 6volt gelcells?
That might be a good, simple straightforward solution.
  Then again, the radio I built only seemed to receive
stellar static. Just a thought.     John Pittelli
