The software CE29 has a help feature press F1 to access it. The TX alignment
must be done in base mode. In other words make sure the base/repeater light is
off on the front panel when doing this and use a wattmeter and proper dummy
load. good luck.

James,
Make sure the repeater is programmed to the proper TX/RX/ pl/DPL etc.
frequencies before attempting alignment as noted in previous post.
Good Luck,

What he is saying indirectly is that your older repeater was meant for
such service ... the VXR7000 is pretty much a barn door (wide open, no
tunig to go anywheres you want). At the very least, you should consider
a better 4 cavity duplexer like a sinclair, I have one at 93 dB
rejection each s
Brian,
I've used the WACom 4 cavity duplexers with 100 watts and no problem...no
desense.
The 7000 has a spurious spec of 85 db or better, but I don't believe much
the foreign companies say. With the Yeasu 5000 they say 50 watts, but for
continuous duty must lower to 15 watts. This is in their

As far as what has changedthe new piece of equipment(repeater) is
by the specs more then twice as sensitive but on the bench it tested
more like 3 times as sensitive as the old repeater. We are going up
today to try some more testing and I will get back to this thread
with the results.

Brian,
As I stated eariler you have dense problem and think it is caused by 7000
tx not meeting specs. Could be duplexer, but if it worked with the 2410 it
should be fine with 7000...only 8.5 db difference. There could be some
desense due to higher power, but sounds like you have a lot more dese
e that is a repeater
that "hears" better than before.

Ok, today we went out on the hill and did much testing. We ended up
running the new repeater on 2 antennas as this seems to work and we
are going to see how it goes for a bit.
Several things were learned while testing things.

Hello All and KFD29 IMHO, if you pose your questions to "the
Group"you may find a "quicker" and more knowledgeable response to
your problems with the VXR-7000; rather than having "individuals" email
you and ask you what is wrong! That is one of the reasons we share in a
"Group". You may e
Make sure you're on the right com port.
Attempting to program a VXR-7000 using CE-27 (using factory cables &
software). No problems in the past. This time around, gives a read error
"invalid data receive". Also, flashes "CL" and "ON" repeatedly, along with
"CLN" on the ANI display...can't remem
Rick;
I think you need to isolate whether it is tx through the
duplexer or something else bothering the rx and or squelch. It sounds
like the tx signal fundamentally is clean from your analysis so far..
in order to isolate through the duplexer, connect the tx directly to
a dummy load i
Rick,
You might check to see if the internal jumpers inside the VXR-7000 cabinet
are single-shielded. I had a VXR-5000 UHF repeater that had single-shield
jumpers with gray jackets and no markings, and had a small amount of
desense. Once I replaced all three jumpers with RG-400/U double-shielded
I don't know what type of service monitor you are using, but I tend to use an
iso-tee to measure desense with the duplexer hooked to a dummy load through the
iso-tee. It might be possible for the service monitor to contribute to some
signal reflection if it is used as the power termination.

Hi Rick -- I am new to the group so I have not seen all of the posts with
regards to your problem on the 7000. However, one thing that
you may want to check is whether the PL is feeding back into the RX from the
TX, if the tones are the same. I have seen this several
times in the past on different
