Actually the Scout uses a 2940 type regulator that is spec'd to
operate at 11V. Some owners have reported problems with running
the Scout on battery (nominally 12 V), but I think most of these
problems are due to weak batteries, RF feedback, or too much resistance
in the line. I found a porblem with my own mobile installation. I
used a crimped lug on the power connector at the battery and found it
had gotten very corroded. Needless to say, now all such connections
are soldered!
For various reasons, I could't run Field Day this year,
so I just operated for a few hours from home powering the Scout using
a 7 amp-hour gel cell. Its great fun using the Scout in a primitive
setup (good drill for the imagined Y2K crisis!)
