Jed,
The receivers are probable AstroTac receivers. Same as the Quantar, just
packaged a little different.
The receiver is just what you think. A receiver on the same RX frequency.
The unit has a 2 wire and 4 wire output, but only uses the 2 wire for most
applications.
The unit puts out a tone
Quickest and easiest method would be to install a ComSpec or similar PL
encode board.
Prices $10.00 to $30.00...

Hi
Does somebody have surplus Maxtrac/Radius lowband high split (42-50) radios for
sale? I'be interested.

Found several sources for the Zetron 15 pin connector used on most
Zetron repeater controllers and auto patch units.
The connector is a Phoenix Contact connector, part number is 1757145.

Jed: I have worked on voting systems from as little as 2 receivers to as
many as 36 receivers in a public safety system. The best routing of the
voted audio is by fiber optic cable, then microwave, then RF point to point
link and lastly and the cheapest by telephone line. If you are using
It's an Onan 4CCK-3R/1J 1800 RPM, 10 HP,
2 cylinder, gasoline, 3.5 KW, 4 KW surge,
from 1965 with 57 hours use on it.
In the 2003 Northeast USA power blackout,
it ran two homes, including two refrigerators
and a freezer.
Perhaps not a home-size unit, but the
advantage is that is sips gasoline

Could you suggest some makes and models and maybe explain why they are
superior to others?

Good surge arrestors/TVSS's are expensive, and like most things in life,

A digital microwave hop (path) and a fiber path... in the real

Some things to think about.
The rated operating voltage of the MOV needs to be greater than the PEAK AC
voltage, not the RMS. During an over voltage event (spike or otherwise) the
MOV conducts, generating heat. The higher the heat the lower the resistance
causing them to go into thermal
Probably the ones I've had the most luck with are the Islatrol series from
Control Concepts. I think they have been bought out by Emerson or Liebert
or one of the other companies that have power divisions. Anyway, they call
these active tracking filters. They not only are TVSS's but also
OK, I should have been more specific. What would be a reasonable unit for a
repeater site that may have only a couple thousand dollars worth of
equipment inside?

with plugs. $75 includes shipping.
Also have a NHRC-2 repeater controller, in a plastic project box with a
multiconductor cable and a DB-25
I use Tripplite Isobar Ultra. Usually ends up with the power
switch rocker blown across the room when hit hard but equipment is well

The MOV I used is labeled GE N4 130L20
The spec sheet from Littlefuse/Harris/GE

I did read through the document, but it is very lengthy of course, and I
