I need some info on the UHF MSR2000 PA. Is the tripler section of the UHF
MSR2000 located in the PA it self? I have a UHF MSR2000 and was thinking of
using it for a link transmitter. I looked on the MSR section here but didn't
see anything about the tripler.
Thanks for any help in adavance

A siren test every morning?
What a great idea.
I think I'll test my car horn and
shotgun every morning when I get up.

The MSR2000 PA is all UHF. Multiplication is done on the exciter board. RF
output of the exciter is around 1/2 watt.

I recall a case where several UHF community repeaters were installed at a
single site. This was not a pretty picture since there was no way to achive
vertical seperation and transmitter combiners/receiver multicouplers were
not as popular as they are today. An intermod study weas run
Hi Dave,
You need a N Male T and the cables should work fine. I like to use the
outside of the cans for the TX RX connections but to each his own. It will
work the way you have it just add the T.

It looks like an older DB-4076. However, the model # on the sticker shows
it's an SP (special production) model.
Between the type N connectors there is a little cap. Remove that cap - do
you see a trimmer cap inside? If so, it's likely it's a DB-4076 or close
relative. If not, then the
Dave,
My guess is that the duplexer was manufactured for Motorola by Decibel Products
from the SP-x on the model identification plate as pictured in your photos.
The duplexer appears to be a pass band type circuit from the separate input
and output coupling loops on each filter and from
Dave,
I don't have to guess about the model number- it's printed on the label.
But, you won't find this unit in a Decibel Products catalog, because it's a
custom-made device as indicated by the SP in the model number. Although
your unit could be a duplexer that is missing one jumper and a tee

We had one law enforcement officer that checked his shotgun while it was
mounted in the shotgun lock, which was attached to the dash.
I think his ears are still ringing from the explosion of the shotgun going off
and the resulting hole in the roof.
Try to explain that to the Captain when

This looks similar to the same setup I have that came out of a Mastr II
repeater. They are definitely pass only. Those little cap covers in between
the N connectors are actually just threaded screws to fill the holes where
Dave,
These look similar to the Motorola T1504 series duplexers, but not exactly.
Look here. http://www.repeater-builder.com/motorola/t1500.html
Your best bet is to follow Eric's suggestion and call DB Spectra for the
exact application and specifications.
Other than that, it appears as

All the DM 4076 pictures show roung cans,
The round can versions came later, first tan in color, then grey, then
ultimately Decibel Tek Black. The square ones were the earliest ones -
they started out a lighter tan (lighter than yours), and then went to that
mocha color like you have. As for

Then the car would be too easy to spot!
The only one with the antenna on the roof near the windshield
The rest were mounted on the trunks.
It would be easy to locate in the parking lot though.
Maybe even add a flag to it???
