priced and seem to be built pretty well.
Our club installed a 50 watt UHF Vocom repeater amp several months

Primus Distribution in Illinois offers a 30-40% discount off Vocom's
list price.
We have been using them for years and have been very happy them.

Dennis,
I have the same problem also. Did you place the filter between the antenna
and duplexer? I have mine installed between the RX and Duplexer. Depending
the WX I can hear the FM Station on my two meter repeater, but thought the

Hi guys,
I'm helping the Wilson County ARC assemble a pair of VHF MSR-2000
repeaters for club use (main and back up). We'd like to incorporate a
UHF Rx in the second Rx slot of the repeaters as a control input.
I'd like to know what the band split options are for the UHF MSR-2000
repeaters, and

Well I think there are 8 or 9 Vocom/Cresend amps I have in service all UHF. 1

There's one on ebay, item #:120085694676.
That's either an opportunity for you to acquire one - or at least to
follow it up to see what the going price is.
Vocom used to be independently owned, but their assets were purchased
at some point by Crescend Technologies (with all manufacturing being
incorporated into Crescend's plant). I guess this afforded Crescend
the ability to market a high end product (the Crescent brand name)
and a lower end
It's a common problem, Moto. fixed it by coming out with the unified chassis
which eliminated the ribbon cable. You might try making up jumper wires to
eliminate the ribbon, you can get edge connectors if you wish, or tear the
ribbon apart for the plugs and start over. It's a pain, but it
Before you shell out the $$ you will want to ask the seller if
it has the male or female on the RX box. They were built
both ways (i.e. backplane=male,RX=fem or
backplane=fem and RX=male) and are a bit of a pain to change.
If you are in no hurry you may want to wait for a RX with the
right sex.
I was working on a couple Mastr II stations with the same problem. A 5kW FM at
the site was clearly getting into the audio. It turned out to be getting into
the high pass filter of the ComSpec TS-64ds tone board. Bypassing the high
pass filter made it go away completely. This was on two
Where did you have the TS-64's mounted?

can't remember, but does the XTR have a busy light that I could use
as a COR? I want to use the radio as a remote base.

The Midland radios work killer on six meters... There is a busy light
but there's also a cos/cor indication on the main board. Don't forget

Oops,
There is a COS point on the main board. A pair of midland radios will
make a great repeater and one will make an easy remote. Much better
that a GE or Motorola. Try it, you'll love it.

What are they worth these days? I have one spare set of MSR-2000 UHF boards,
one receiver, one exciter - both with channel elements in the 460/465 MHz range
(will tune to the 440 Ham band no problem). I was just getting ready to put
them on ebay, as I used to get $250 for the pair a few years
I have been told that this is a known problem. The fix is to use a unified
chassis. I may be able to hel;p you with a unified chassis.

Hi All,
I recently listed two Kenwood TM-541A 1200MHz radios on that auction
site both have the COS brought out and terminated on the back. They make
great link or repeater radios.
I have also listed a Wacom WP-698 BpBr 4-cavity 1200MHz duplexer and a
Celwave 900Mhz notch duplexer tuned to
If i'm not mistaken It was put between the duplexer and the
antenna. The site I used i no longer use. The friend still uses his
site and the dci filter i loaned him is still in line and doing the
job. I think he also uses it between the duplexer and antenna.
