[TenTec] Scout 555 noise floor.

[Stuart Rohre]

Another thing hams often overlook, is to twist the heavy conductors used to
go from a DC supply to a transceiver to reduce any chance of stray noise
pickup via that path.  Although I do not believe it to the cause in this
case, it bears mentioning.

Always be alert also to heavy noise sources that can crop up in an area with
old overhead electrical wires, substations, vapor type street lamps, or neon
signs.
