Welcome to the world of 6 Meter repeaters.
They can be a lot of fun. In Missouri you are a little better off frequency and

For radios it depends if you are a GE or Motorola person. If you are a GE

The PLL exciter is why you're having such good success running a 4-cavity
duplexer. If you had a PM exciter, chances are you'd be experiencing
desense. The PLL exciter produces about 22 dB less noise at 600 kHz offset,
reducing the noise supression requirement of the duplexer by a like amount.
Rich,
While there have been a lot of good suggestions thrown at you, you are fighting
an uphill battle without knowing the spec's that were obtained when the
duplexer was re-tuned the last time or finding someone with a tracking
generator or network analyzer to verify the duplexer tuning.

I had one fellow who always insisted something was wrong with the repeater
when the foliage came on the trees every spring. I tried to explain to him
that the leaves and humidity were attenuating the signal and that it was
just a fact of life for the fringe-area users.
Not all voltmeters behave the same with complex AC waveforms (such as
noise). Some of my Flukes are inaccurate at higher AC frequencies (like
above a few hundred Hz) - and they're spec'ed that way. What kind of meter
are you using, and where are you measuring (speaker terminals is where you
I agree. Put it back to the original output. I always like to turn
my stuff back at least 10%.
Turn the beep tone up in volume, tell them you increased the power. see
what they say.

John, here's a more subtle lesson on repeaters,
Or speed up the CWID one or two WPM, or change to a slightly higher tone
frequency. Top 40 stations sometimes still do this trick (pitching up their
CD players or automation system playback speed maybe 1%) - some PD's are
convinced that it improves ratings for one reason or another...
I have tried with 3 volt meters and 2 SINAD meters: a Fluke 77, a Sinadder 3
(SINAD AC voltmeter) and a HP8924c. Pretty much same results with all. That
is 20 db quieting around 0.7 uV, SINAD around 0.35. So what's the recommended
meter? Should I trust the SINAD reading and chock the quieting

Anyone have one of the above they wish to part with? We have reason
to suspect the PA in our repeater.
It has developed various intermittent behaviors (dropping carrier,
distorted audio, varying output, etc.) ..
I believe this to be the 60 watt PA for the GE Mastr II Exec II
mobile radio
I believe you are talking about an Exec II.
Several places to check before replacing the PA.
A common problem is the jumper between the exciter and the PA. The RCA
connectors sometimes go intermittent. Also, if the TR relay hasn't been
jumpered, it could have gone intermittent.

Guys .I have a similar problem with 2 repeaters but its in the receiver side
.The maxon sm4450uhf receiver is tuned to the best it can be on the service
monitor -115db and the bpbr duplexer is tuned to correct specs as far as I
can see on the hp8921a .I have also tested the repeater in duplex mode

This is either an Exec II or a Mastr II - two different radios. The Exec II
mobile is 'gray' and has a plastic, non-movable handle. The Mastr II mobile
has a foldable handle. Which one do you have?
