He said easy and simply. The receiver would be in ctcss
operation. I make and install mic jack plugs for full time
ctcss operation, which also protects against magic fingers
and curious people near the equipment. You only need to
ensure the receiver decodes ctcss to remain reliable.

It's done all the time...
So keep "someone" away from the controls. Simple enough
to do when the equipment is under local control.

Doesn't take much to check a basic antenna system out
before operation if you suspect a problem.
I now use a special antenna - providing its own ground
plane so much of the 1/4 and standard base loaded coil
problems don't happen where I use mag mounts. Many an
antenna system demon have been put to bed with a simple
antenna change. It's one place in addition to the flea
market where I'm getting all the surplus Maxrad,
Antennex, Comtelco and Larsen antennas to play with
as mentioned last week.

I understand your reasons, but he said simple and easy
so we go with that thought.
