Hello All,
I am looking to rebuild a 70cm repeater with an output within the ham band. We
currently have a non-tunable fiberglass comercial band antenna wich is giving
us a SWR of about 2:1. The first piece of advice we are looking for is
recomendations for replacing the antena. There are some
One other thing I forgot to mention is that we would like the repeater to
contain the ability to run with a PL tone.
Thanks again!

I've used GE mastr 2. swap out UHF receive section with a VHF receiver.
Duplex radio and your all set. Lots of guys do this for split site 6 meter
repeaters. I think you can find that info on the repeater-builder website
some where.

We are using Motorola CDM-750's for our sites. Mount both radios to a 1U
19 rack shelf, and using a 4 hole saw, cut a hole below the TX radio and
mount a 4 Dayton 24vdc fan, they run forever!
We simply use the Motorola R.I.C.K. for our controller so to speak.
Simple and reliable.

GE MVPs are the best answer I've found hands down. Swap a VHF RX in a
UHF frame. You can use a MastrII or ExecII for the TX site and it's all
very neat.
Even cooler - MastrII RX and TX's convert to 220 pretty easily. While
the conversion is not for the faint of heart, 220 links are cool.

From the information you've provided I'm look hard at a Motorola R1225
or a pair of GM300s.
The diamond will certialy lower your SWR, but so will a 50 ohm dummy
load. Low SWR isn't the only concern any more than antenna gain is.
It's likely the Diamond will work, but these ham market antennas
Andrew,
First I would try to find a site like Ham that has a big tower, a
tall building, Farmers Silo, water tower or grain elevator to locate your
repeater on. You may also need a small shed to keep your equipment in.
Use a quality antenna don't use ham grade antennas like jetstream,

I know nothing about it other that what the auction shows.
It's just too amazing not to share.
The auction is for an SP version of the UHF micor repeater which
was apparently never put in service and was shipped from Motorola

Joe,
How about Motorola Parts? The exact replacement for the M9839 is still
available as part # 4811043C12 (AKA 48R00869839), at about $ 1.50 each.

It is DES capable meaning you can transmit encrypted communications
through it. It does not encrypt transmissions it only passes what it
hears. I believe that is the way it works. Should be easily converted
back to standard Micor.

Judging from the modules that are in the unified chassis, it appears that
the station is a standard DVP (Digital Voice Protection) repeater. The SP71
merely means that it was manufactured to operate in the 440-450 MHz band.
All of the modules I would expect to be in a DVP station that can

Depending on what coverage you are looking to expect, will help you choose
the proper gain antenna.
A higher gain antenna is not always a good choice and can cause more
problems and poor coverage then you would expect nearby the repeater.
What is you HAAT? Are most the user going to be fixed
Eric,
Thanks so much, that is the part number I needed. Got some coming my way from
Motorola Parts. I just did not have enough information or a good enough source
to be able to cross the number over.

I have a commercial UHF repeater that has been on solar power for seven
years. I have two Concorde 205 Ah AGM-SLA batteries that are always at 100%

I used a Comet GP9 for about 2 years on a 444 Mhz repeater, then connected a 2
meter repeater to it. The 2 meter system performed FAR better than the UHF
system. Both repeaters were nearly identical in performance otherwise, the GP9
simply performed much better on 2 meters.
