Acquisition cost for Tait units was high, however they are very
reliable, and excellent RX units.
Have seen more than a few on Ebay other places quite cheap, saw a 100
watt unit on ebay last month, $300.00.

I am aware of the reasons to not use LMR-400 in a duplex environment, but I
have a question I haven't seen asked before.
Is there any reason why the direct burial version of the cable would be better
or worse on a repeater? Would the stickey glop in the cable make a difference?
tnx for any
Ed,
The RF Technologies repeaters are as good as they get. Ron Tilley is a great
guy to deal with and also a good friend and business guy.

I'd tend to think it might be a little better, less oxidation of the braid
and foil, and less movement. I only buy the direct burial (DB) version of
LMR400 anyway, it's only a few pennies more per foot, I figure it's worth
the little extra protection if it gets a nick in the jacket. And, of

Hi,
First thing. Remove the preamp. Those things are only useful after you have a
tight working system. Otherwise they can pick noise and that is all you'll
hear. To get started, start simple.
Be sure the antenna is tight. We use the G7 and found one that came loss at the

John,
Get the preamp out of the circuit and **powered down.** Preamps will
take any desense probelm and will make them worse - usually at twice
the value of their gain.
Do a 'binary search' - Start by getting it to work without stuff.
Disconnect the antenna and feedline and put a dummy load
Hello Group,
I have bought many Tait T-855 UHF repeaters both on E-Bay and from private
sources. They are excellant units and I now have 7 systems online and working.
They are stable and provide crystal clear repeater communications for our GMRS
network here in Georgia.
My first question is what frequency does it operate on and, then, what kind of
RFI will it cause?

Did try that, no luck. I did manually key it by applying 5V to the gate of the
FET. That did work. Does look to be CPU, since it drives the FET directly.

Sounds like RF to me.

Some comments and observations;
Moving a 30 or 40 year old might radio invalidate the fact that it was
working at the other site.
Duplexers, particularly 'vintage' duplexers don't always travel well.
This is particularly true when the person doing the alignment forgets to
run the locking
Except that you need to despread the pilot. The good news is that some
companies make saw correlators for the pilot. Bit of work regardless.
