The phenomenon you are seeing is because the 1/4 wave size at VHF is

Most likely, your HT is part or all of the problem.
The CTCSS is supposed to be injected after the limiter so this problem
(called talk-off) does not happen. In some radios, the CTCSS is mixed
with the mike audio prior to the limiter, and then, talk-off happens.

At 01:24 PM 12/24/2004,
Ralph,
The symptoms you describe are those of CTCSS distortion due to limiting
of excessive deviation.
If your authorized emission is 20K0F3E, the sum of voice and CTCSS
deviations cannot exceed 5.0 kHz. The measurements you cited for your
test bench HT reveal excessive deviation at 5.15 kHz.

Ken,
Please advise exactly what frequencies these pager transmitters are
operating on. There are a number of possibilities for intermod, but
knowing the offending frequencies is crucial to a solution.
Less than a mile from my home station, there is a hilltop site at which

Maybe it's like a Grade A Ham? ;-

Excellent reply, Eric.
I worked for several paging companies for about 10
years. Although several problems I found in the past
were caused by the paging company, just as many were
found to be shortcomings in the repeater equipment or
faulty hardware on the tower.
Like you said, we really
We have a problem here in Temple, Texas where one paging carrier operates a
152 system and another has 157 about a mile North of the 152 site. I cannot
remember the exact frequencies, but 3 times one minus 2 times the other hit
147.240. This only happened when both paging transmitters were
All paging transmitters involved should have narrow bandpass cavities
and circulators on their outputs. That's usually considered a must at
any site. If the paging company isn't willing to spend the money for
that, then they aren't to serious about staying in business.
The good news is that
You will find less and less narrow band cavities on paging transmitters
lately. As the paging industry slowly goes into their death spiral of
loosing customers, they no longer need 2, 4 or more transmitters at each
site to deal with the capacity of pagers out there. What some companies
are
Except that the vast majority of VHF transmitters/networks weren't
really capable of multi-freq on the fly as you describe. At least around
here, anyway, they were virtually all Micor PURC stations.
And most sites would not have allowed the transmitters to remain without
cavites anyway.

The paging companies were more up to date here in the Northeast, Motorola
Nucleus and Glenayre/Quintron equipment. Some were capable of up to 16
frequencies in the same band.

Joe,
Do you have any info on the Motorola Nucleus gear... I have a high power
PA for 900MHz that I thought about trying to make use of, but can find no
docs...
TIA,
