Does the entire page happen, or does it abruptly stop part way through some

in the mix and dropping before the pager does.
However, I had a situation where there were four paging sites scattered in

It seems to pick up most of the page. Occasionally the beginning is missing or
it will get just the very end. It always seems to drop at the same time as the

No, I never, ever have heard any other audio. But there is time when I don't
hear it at all... as if it takes two signals to occur.

Does the repeater run CTCSS on the input? If so, is the behavior the
same if CTCSS is off? (CTCSS mig
Many times (but not all), there will be a grungy sound with the spur.
Think of a very loud 60 cycle hum.
And 15 kHz is higher than normal. I think the typical shift is 5 kHz
(+/- 2.5 kHz) if we are talking about digital paging. Analog might be 15
kHz, as the bandwidth limit would be 16 kHz.

Yes the repeater has CTCSS but I turn it off for testing. When on the CTCSS
will false but that's not what I'm talking about when I say that the repeater
sometimes keys up after the beginning of the page.
I'm going to take another repeater which has a different 1st IF up and test
with just as
I haven't noticed a hum. There's more of a scream on it.
It's POCSAG. Is that analog?
The dev is basically 15 Khz but there is, what I going to call splatter that is
like 30 Khz.

Before you said 15 kHz P-P (IOW bandwidth). Now you're saying 15 kHz
deviation. 15 kHz deviation would be way too high.

My service monitor (HP 8924C) has both a deviation meter and an oscilloscope to
display the demodulated audio. Both the numbers on the dev meter and the peak
to peak on the scope read about 15 Khz.
I see another paging system (152.84) that shows the same 15 Khz dev, and a
bunch of other ones

There is something wrong with your SM, then, as it should not show a
deviation of 15 kHz on a signal that is 15 kHz P-P unless it's only
deviating in one direction from the carrier.
The +/- 4 kHz sounds about right. But, it should be centered around the
carrier frequency of 157.740 (Or, on 157.

The meter reads P-P just like the scope. I generally set dev with the meter and
confirm it on the scope. But your right, this really doesn't matter. I was just
making sure they didn't have the dev out of wack and from what I gather here
they don't.
We're going up Tuesday with another repeater a
Apparently, from what the tech said, this one is slated to go off the air in
coming months, too. But I can't wait that long as our repeater is basically
useless at this point. And you never know, it might take them longer than that
to actually kill it.

If that was the issue I'd think every other two meter repeater on the hill (and
there are many) would have the my same problem. But they don't.

Here's the latest: We went up to our site yesterday. We added a lighting
arrestor to the receive antenna. We grounded the chassis/rail/cabinet as it was
only grounded via the power cord previously. Didn't expect this to fix the
paging problem, it just needed to be done.
I did find a loose UHF
I've seen this before on Wacom BpBr duplexers. Remove the coupling loop from
the cavity and re-solder the connectors. Use 2% silver bearing solder if you
can find it.

This is a couple of pass cavities, not a duplexer. Do the band pass cavities
have the same problem?
