The telling point it to measure the output power with none, then one,
then two uses in line. I think you will be surprised at just how much
power even .7 of a volt costs you. I remember seeing a Icom 22
go from 11w to 6w.
This power loss is why many radios have a diode connected in
reverse
This is true - and still no FCC rule PREVENTS you from adding it.
I STILL like having every TX in a system have a unique ID for the
same reason as I said earlier: if someone is hearing one of my TXs
someplace it shouldn't be and they can catch the ID it tells me
which TX to look at.

The only problem with rubber bands is that most are
square, and have a tendency to jump during the flat
spots. I've used thin O rings cut to size with great
success. Being round, they turn smoothly.

You can try the phone company. I have had great success getting 1200' spools

to bury with the electric cable. The only problem is you will need to do
this several times and do some splicing to get to your 3500'.

My bet would be that the black wire fuse is there for positive ground

is hot, and you would need the fuse there.
