Pole? 70 feet
in the air! Read on... (about Pahrump repeaters)
2-25-2018 a project was worked on to move the Amargosa 2 meter repeater
event was attended by:
Kent W7AOR representing the NARRI group as sponsor of the repeater.
KG7KA hosting the location.
N7UPP who did all the ground work.
finally the pole climber, Janet Arrett (not a ham)
started out with 2 brackets made by Bill KF7DHE to mount the antennas
on the power pole.
Actually it started a lot earlier with the pole and shed being provided
by our local radio station KACE (KACP 103.1 in Pahrump)
The pole has the antennas for the radio station that you can see in
We also use the pole for the antenna for our Fiber optic over the
air broadband provided by the local power company VEA
So Janet had to manuever around all these other antennas on the pole
to install the repeater antennas.
The top antenna is mounted at 70 feet at the base and will be the
receive antenna hoping for full valley coverage.
Next is the tranmit antenna mounted at about 35 foot level. The antennas
are about 10 feet tall.
This makes a separation of about 25 feet between the top of the transmit
antenna and the bottom of the receive antenna.
interesting (and scary) thing is that Janet is just 5'2" tall
and the pegs on the pole are 3 feet apart. It was scary just watching
her do this.
Anyway after many hours, the antennas were installed. Then Kent and
Mark got all the equipment moved around and connections made between
the various units in the shed so Kent could program everything. All
this happened while Loren ran for tools and watched.
anyway here are a few pics of the operation.
first one is Janet just starting up the pole. Second is when she was
about halfway up. Third is at the top. Last 2 show the antenna and
There are videos of some of the operation if you want to view them.
I posted them on Dropbox and the links are in this
Kent configured the antenna late into the night. Unfortunately it
did not work correctly. The unit I.D.s correctly and activates when
keyed but no audio is transmitted. After much consideration and frustration,
Kent gave up and went home discouraged. Next we need a tech to come
and solve the problem.
to Mark K7UPP for an outstanding job helping to put it all together.
He drove out from Vegas just to help- What a guy!!
for the finished job. Here are a few shots of the completed installation.
first photo shows the 70 foot pole next to the radio shed with some
antennas for the country radio station here in Pahrump.
Next is a pic of the inside of the shed. It is fully insulated and
air conditioned. Last shows the repeater and the ground wires.
Was able to provide one continuous 6 gage copper wire to all 3 boxes
and out to a ground rod outside.
The antennas are terminated to a lighting arrestor and also
connected to ground.
is the ground rod attachment. Second is the ground block on the outside.
Both arrestors are grounded and the ground line goes inside for the
Saturday March 2, Jerry N7HYN came over to check it out.
He determined that the duplexer was connected incorrectly and reconnected
it the right way.
He also checked the receiver and transmitter. They both work well.
In fact he said the receiver was "Hot!".
It was also found that one coax jumper was inadequate. Kent ordered
a new one and it got installed a few days later.
Ran a few tests and the system seems to be working well.
Currently the repeater is on IRLP 3194 and Western reflector channel
1 at 146.910 minus & 123 PL.
If you visit Pahrum, try it out. Or if you connect via Echolink World
conference, you will be heard in Pahrump.
is another repeater in Pahrump on 449.750 located in central Pahrump.
This one is connected on IRLP 3491 and Western Reflector channel 0
and the Hi-Gate conference. This repeater switches twice a day for
the World conference nets.
