The Motorola document is based on the use of the Spectrun base loaded
antennas sold by Mother. The Spectrum antenna is a series coil
arrangement, not a shunt fed or tapped coil; this is very important!
The chart works quite well for the Spectrum antennas and will probably
work for any
Tim,
Digital paging (mostly POCSAG coding these days) is FSK and will
easily occupy 15KHz of bandwidth.
On a Service Monitor deviation screen you will see a square wave
pattern that looks like it is overdeviated unless you are very close
to the transmitter in question. Read on and you

The interference is pretty strong. It competes with my base station
on low power. I'm 25 miles from the repeater.

Martin,
The other 40dB is hiding in the lower regions of the sweep.
I'll try to describe what to do from memory but I may be a bit off target.
The bottom of the sweep should look a bit wide and ragged, not a smooth line.
Drop the Reference level down to -40 or -50. You should now see the
bottom
Most likely an old RCC mobile phone. Full duplex mobile, check for
multiple channel elements crystalled in the 454/459 area.

Been following this thread for a while, some thoughts in random order:
If I remember correctly you said that you are using the 1 5/8 heliax
notches as your duplexer.
If I also remember correctly others have reported problems of many
sorts with these homebrew devices.
While not an easy thing
Taking a bit of a guess, since the board appears to be some sort of
encoder or decoder for audio,I would suspect that it could be used as
a single tone burst encoder or decoder. The CG module position would
have provisions for PTT and audio out as well as disc. audio in and
squelch
According to a quick Google search it shows up as a MastrII 50 watt
36-42 MHz PA and heat sink assembly.

We have a TON of service manuals available for sale. One question
though, is that a typo on the model? I thought all Kenwood product
lines were TK-XXX.

Paul,
It depends on what portables you are using with the Kenwood repeater.
Some, but not all of the newer CPS programmed equipment have a setting
checkbox marked something like Use non-standard PL decode which can
be set on a per channel basis. With this feature enabled the squelch
If i read your post correctly, you are trying to achieve omni coverage
and downtilt while maintaining a high level of antenna gain.
I think that you will only achieve what you want by using electrical
downtilting in the antenna. Otherwise you are going to have to trade
off something.

In your initial post ypu mentioned that you had to use pliers to
tighten the connectors on both ends.
2 possibilities:
1) You used the wrong connectors.
Yes I have seen this done before. A PL259 screwed onto a N-Female.
