While digging in the garbage looking for blackmail material, I found this:
It seems, on 05 Aug 96  08:52:00, that Bill Funk and Glenn Fetty
were talking about RE: ALT POWER FOR BASE SCANNE.
Now I have them!

That's what I do here. But even if the radio drew more it would still work
if the blackout was only a few hours or so. Either way it works great for

sometimes when they switch transformers.
