If I could afford that equipment I would do that. However
the thought of spending as much on test equipment as a new
car is a little tough.
We do have a service monitor in the group I hang out with
but it does not have a tracking generator.

Totally understand. Although many good service monitors can be had for
the price of a USED car, not a new one -- if that's

right now and we have to get it back. The person who owns
it actually has 2 of them but one needs some work and he
is probably going to sell it rather than fix it.

Hi!
I need information about how to make conection and wiring for a
repeater using radios tait 2000 .
All informatior are welcome .
Thanks .
If your repeater is located at a cell site, check this out:

Good reason to increase the lease price...
Interestingly, the TRS is NOT hooked into the generator at the towers in
one county local to me. The county has to bring in their own generators.

Hello All,
I have a requirement to install a battery backup system at a local
ham repeater. It's a GE Mastr II running about 100 watts. With that
much RF power, a couple of 100 AH batteries is only going to last a
few hours.
My first thought was to add a second lower power RF amp (something
Dwayne,
I have done exactly as you said with a relay and a second pot. It works well.
The only problem one does not realize the power savings one might think
although it is a noticable amount. The reason is if you look at a MII PA
running 100 W its current draw is about 20 Amps. by reducing
Hi Guys,
When reducing power levels on GE PA's, be sure and check the output
on a Spectrum Analyzer for spurs at the reduced output power level.

What do you plan to use for batteries?
If you have some flexablity I would use four 6 volt golf
cart batteries. Best bang for the buck you can get. You
should be able to get 235 ah batteries for about $82.00 a
piece that means with 4 of them (wired the right way) you
can get 470 ah for
Tony,
Every cel site I've visited here has its own generator and fuel now. The site
my 2m repeater is on has 5 cel carriers and each have right on the equipment
plat forms a generator, at least 10 kW, with at least 500 gal fuel tank.
This is a 3 FM site and they also have their own large
Thanks. This is a great write up and one for the
archives. As soon as we get over to pickup the service
monitor (and some free tower sections) I will let you know
the specs on it and we will start trying some of these
tests.

Dwayne,
You raise an excellent point! The first question I must ask is, do you
really need 100 watts? Since a repeater's range is limited primarily by how
well it can receive distant stations (primarily handhelds), you may have far
more transmitter power than necessary. Maybe 20 watts is all
Ed,
That won't work for us as we only have two stages with the GE
equipment, 250 mW from the exciter and 100 watts from the PA.
I'm sure there is a way to split the driver from the final, but
that's really beyond the scope of this project.

Eric,
Obviously we could probably get by with less power, but I still want
to reduce the RF power when the AC is out to maximize the battery
life.
We tried the trick of lowering the power to 10 watts without telling
anyone and a few people in the fringe area that are regular users
could not
