Hi Steve,
Based on my most recent dance with LMR feedline I don't use it in
any duplex radio system. Nor to I try to use it in any half duplex
radio system. The last horror story was a local club repeater. Some
yet unknown person replaced the coax cable from the circulator (IMD
Panel) to
Motohead (Motorola) had semi global names for some of their
equipment lines although you didn't see them mentioned as much
as you would expect.
Research Line was one such name although I'm not sure of the
dates and equipment it was assigned to describe. Probably the
wonderful Sensicon
Hi Tom,
The bp loops are pretty much just an SO-239 and the matching metal
loop if you wanted to build some. I probably have diagram'd out the
demensions of both the loops and bpbr probes if you end up having to
roll your own.

I know of no Beacon that monitors first. That's why they are called
Beacons. They also usually have strict timing requirements in order to
enable frequency sharing that any delay in TX would destroy. (Beacon A
TXs on the minute, Beacon B at 10 seconds after, Beacon C 10 seconds
after that, Etc.)

You don't get 16 selections.
If I remember correctly when the high order bit goes on

The problem is. Using a battery on a power supply is that unless you run the

That same battery would probably run your system for weeks if it were 12 or
24 volts and hooked directly to the appropriate battery backup point on a
repeater. Lot of inefficiency when you have to chop up battery and convert
it to 120 volts AC. Just the nature of the beast. Sometimes
