Not sure which kind of duplexer Motorola uses in the
MTR-2000 but in the MSF5000 they use a Tee Duplexer
and a TFE6492A tx filter. In my oponion it works like
crap.
The duplexer that I like best is the the Cellwave(RFS)
or Phelps Dodge style 526. I am using these with 2 UHF
C74clb MSF-5000
Looking for a Decibel Products DB408-B 450-470mhz Omni antenna.
Please contact me offlist. [EMAIL PROTECTED]

I have had good luck with the TX/RX brand as well,
even at 250 watts with a gasfet preamp.
You should have no problem tuning a used TX/RX
duplexer from the 450-470 version to the 440 band.
I have several of these and they all work good.

Joe,
I recently installed a complete MTR2000 UHF 100 watt repeater for my
employer. The duplexer that came with the station was a Motorola
TLE9022, which is a premium version of the RFS/Celwave PD526-4-2. This
is a six-cavity duplexer that is specified at 120 dB isolation, minimum,
and 1.3 dB
If you want to move a TX/RX used commercial (450-470) duplexer, you
should order the cable kit from them to be able to maintain good specs.
I moved one from 460.??? to 441.5 and it wouldn't make specs with the
shorter harness. I ordered the longer kit and it tuned up great.

sorry, disregard that bandsplit correction, original was right.

Correction on below bandsplit should be 460-470mhz.

As per recommendations on this group I have settled on a DB-408 for
my new UHF repeater project. My problem is I keep running into dead
ends in locating one, new or used, to buy cut for the ham band. I
talked to Andrews to see if I could persuade them to build me a one-
off for 440 but hey
Could some kind moderator look at my account and perhaps stop the flood of
triplicate e-mails 484 in 5 days is a bit much...thanks!

You can also look at Telewave. They make one similar to Sinclair, but less
expensive.
However, I have yet to see one of the Decibel 450-460 versions that didn't
work just fine in the ham band. I'm running that band split and my repeater
is on 442.75. No problem at all.

Hi all, I was wondering if any of you are using this machine on the air, and if you had any bad experiences with them. Are they reliable? I just purchased one on the used market for a decent price, and was curious on the history of it. Also, I've noticed that if I connect my CAT-700 to it and
I think they usea celwave (RFS Duplexer) I am actually trying to find the model number now

Thanks very much. That may be the cap I am looking at it was actually on top of
the base-emitter pins. Thanks for the reply I never expect it so quick.
I still can't find any spec on the M25c19. In fact I can barely get
any hits on it. Have you heard of replacing it with a MRF654. Or even
I have been running a LDG Voter for the past (4) years now, with (5) receivers connected to it. No problems encountered with it. The big benefit with the LDG over the various others units including Motorola ,GE, and Hall is the visual settings, active channel status and programing.

I agree, I have 13 LDG voters in service.
You should know the LDG and Hall voter cards are
not true signal to noise voters.
The Motorola, JPS and GE voters are true signal to
noise voters, the JPS voter in the digital domain.
They all work very well, the non sig-to-noise
voters can/do
Scott,
After you pulled and bypassed the final, what was the lowest power you
could get out of it while still being stable? I'm thinking about doing
the same to a VHF maxtrac to use as an exciter for a cont duty PA, but
it only needs about 400mw to drive it to full output. Thanks.

Tom,
I'm not sure of the exact model number... but I do
have a ham band designed and spec'd decibel UHF dual
2-section 408 antenna. The model with two 408's
stacked and it's a real nice monster.
Do you need the measurements for the harness
or some other item spec?
I'd sell it, but
You may feel free to apply accordingly ...
