Amateur radio can be a valuable backup for Fire, EMS, and Police
communications systems. There are occasional Simulated Emergency Tests
preformed to uncover deficiencies in primary systems and once uncovered,
these need to be addressed. Our Cities and County bought a radio
communications system
Unfortunatly you will need to swap out the range 2 exciter and receiver for
range 1 units.

Marty, did u ever get ur MVS programmed? I have the stuff - just
haven't used it in years. If I can find a working MVS, I could put your
eeprom in my radio and program the chip without having to ship the radio.

This is a follow up to my original post.
The tower crew showed up yesterday to swap out the antenna. Once at the top
of the water tank, we had them connect a dummy load to the top of the
feedline and discovered that the feedline itself had a poor VSWR.
They disassembled the top
Hello,
Does anybody have any 100 Hz tone reeds for micor repeater station? I
need encode and decode. I need at least one set, but may be interest
in a few extras if the price is right. Thanks,
Jordan
You can also contact me off list I have run several of these for over 10
years

Bottom line: Almost all the advice I got here was 100% on-the-mark. Thanks
to all who contributed. and please don't shoot me for not replacing the
hardline. I don't get to make those decisions!
I wouldn't worry about
Someone decided to pull the hardline out of the shack - I
think the idea was to remove the bottom 35 feet, which had
been spliced on using a hardline splice) to test the two
sections individually. As we uncoiled it from where it
passed behind the shack, next to the chainlink fence, the
Mike this very same thing happened on a 47Mhz simplex base station -
poor range, high vswr. Fold over monopole. Dummy load, still bad,
replaced RG8 between the building and the antenna, still bad. Pulled a
little cable from the building and there is was - RG8 blown up due to
lightning.
Actually- I disagree. Ham or not- you should repair it the right way.
At the very least you need to replace all the equipment, feedline,
connectors, antenna, mounts, wireties, and anything else associated with the
system. You do not want to take a chance on any of your equipment going bad
Yeah, and your repeater is probably responsible for the Honey Bee decline as
well as the Lightning Bug becoming extinct. Durn Ham radio operators!

LOL! Actually, we were discussing having the county add 10 feet to the legs
of the water tower, but when we realized that we'd have to recoordinate, we
changed our minds!

Ground kits at top and bottom of vertical feedline run (before any bends),
and another ground kit at the entrance port to the buildling/shelter.
Polyphasers inside the shelter mounted to the the common-point ground bus
bar for all of the indoor equipment, with the indoor common-point ground
tied
I'll second that!!

Actually having worked for the water company, It would be easier and cheaper
to have them get a group of earthmovers and remove about 100 ft of the
surrounding
land. That way the footings, piping and all the ground associated with the
tank can be inspected at the same time. I would remove the
To add to this, the transmitter is dip switch so the rx is the
problem at this point
it looks like the tx will go wherever needed.
My tx module has modulation issues too but that is another matter...

There are two pots in the TX SYN, but that would be a last ditch thing.
Usually you can make everything work OK in software. The pots inside
