A quick visit to the site revealed some workers had tripped the
breaker on the circuit powering the repeater.
I wonder if someone tripped the breaker or if it's just getting tired?
If it trips again, it's probably time to replace it. Hope it isn't a
long trip out to the site.

Hi Paul
the only way i found to dec. and enc. pl/ctcss is from tx and rx side.
u need to go on tx and make af gen 1
to 300Hz to filter the ctcss and tx from radio don't make noise
all athers to 1khz or 1.5khz
from the rx side just insert pl/ctcss in af gen 1 and send signal from
amplitude and
Eric,
You may have lost track of the fact that this is a site to ask questions and
people knowledgeable in the subject answer. (Note the answer Bruce gave to
the question) The answer you gave makes me wonder if it isn't time for you to
step back and re-evaluate your position on this board.
This suddenly got me wondering, I plan to try ATV, and would it
supposedly be a violation of the rules sending when you don't know if
anyone will actually receive it?
As far as a QST, that could be considered as a one way transmission when
you really think about it.

Some workers at the site were painting the chain link fence with a bright shiny
silver paint, and they ran an extension from the circuit to their big
commercial paint mixer. Guess there was not enough headroom left in the circuit
for a giant motor!
As for the drive, its a killer! 5 minutes
I was in a group that operated a 426 MHz ATV repeater (transmitter) for over
10 years in Dallas (1980's), whose initial purpose was the rebroadcast of
color weather radar from a local TV station for mobile storm spotters. This
was well before the days of the Internet providing free and easy

We added an extension to this system in Greenville, Tx (about 50 miles NE of
Dallas) located on the roof of the local hospital. We had an input on 426 with
a beam for the Dallas feed and on 43x? to allow local crossband repeat to the
900 mHz band. We later installed a 1296 input when a radar

Yes, of course your right Rick, but.there are always those that just 'have
to' let all of us know what they think or know, because they are the ones that
are right.

Jim, I thought our groups experience would add some useful info to the
interesting posts. You do not know me, so I am not sure how you can say that
about me truthfully.
We were involved in the system here in the North Texas area for many, many
years and it was a mainstay in the storm spotting

If it were me asking that question, I would be saying thank you to Eric.
Not everyone knows that some of the commercial manufacturers are very
supportive of ham activities and that they have that sort of information
readily available.

If I thought the new discussion was inappropriate, I would have said so. I
am OK with discussions as long as they don't get out of hand.

The 642s were provided with either UHF or N connectors
depending on the customer request.
Murphy's Law says the matching feedline lead from the outside
world will have the other type connector.
The cable lengths were selected at the factory to meet the

The FCC will also give you wide lattitude to break the rules if you can
demonstrate the operation served a public need during times of emergency,
was used only during such times, and didn't interfere with other providers.
Sounds like you qualified.

Oh yes I remember Hank well, when Phelps Dodge had a warehouse in So.

They are both copper.
Nothing wrong with both shields
Hank sent me a couple of barrel connectors made by PD that I've never seen
before or since.
They are UHF on one end of the barrel and Type N on the other end and Hank
insisted that
the connector produced no vswr bumps up to 500 Mhz.

channel digital output board and the NHRC DAD (digital audio delay). The
