The following photo sequence shows the Fallbrook Amateur Radio Club
("FARC") in the process of moving its repeater equipment from the American
Tower Corporation ("ATC") site on Red Mountain, to the California Department of Forestry
("CDF") site next door. First, a bit of history:
October 1997: Art Rideout (WA6IPD) -
who has graciously provided FARC with repeater service on 146.175 MHz
from his home near the base of Red Mountain since 1989 - indicates that
he will no longer be providing that service for FARC. The club
thanks Art for the many years of service, and selects the ATC site at the
very top of Red Mountain as its new repeater location, thanks to the
efforts of Bob Morrow (WB6DIJ) and others. FARC then officially
coordinates not one but two repeater frequency pairs for use on Red:
146.175 and 448.900 MHz. Chris Durso (AA4CD) builds "new"
repeaters from scratch, relying on used and donated equipment for the
most part, and the labor of love is free. Thank you Chris and Bob!
March 1, 1998: FARC begins repeater operations on Red Mountain at the
ATC site using 146.175 and 448.900 MHz. A substantial amount of pager-like
intermodulation interference is received on 2-meters - interference that
proves to be hard to eliminate. To work around the problem, FARC reduces
its 2-meter transmitter power and uses two separate antennas on the 2-meter
machine - one for receiving and one for transmitting.
August 4, 2000: The UHF repeater
frequency is changed to 445.600 MHz after the band is restructured by
regional area coordinator SCRRBA. Later, ATC - on the verge of
bankruptcy - asks FARC and all other tenants with free rent to vacate the
ATC sites nationwide. FARC casts about for a new site and thanks
ATC for the secure facilities they have provided.
September 2004: After a long period of negotiations and paperwork, FARC
moves its repeaters and antennas to the California Department of Forestry
("CDF") site on Red Mountain. This will hopefully be a permanent home for
the FARC machines, and the facilities provided by CDF are truly outstanding.
September 18, 2004: FARC begins repeater operations at the CDF
site. The new site is sufficiently removed from the old site that the
2-meter interference is virtually gone, and the UHF spectrum is
exceptionally clean. The photo sequence below shows the move in a
step-by-step fashion. Thanks to the many individuals who worked tirelessly
behind the scenes - beyond those pictured here - to make the CDF site happen!
FARC's 4-bay omni-directional 2-meter antenna is assembled by
WD6AHX and AA4CD while KG6HSQ observes. FARC's 8-bay directional UHF
antenna, a DB-413, lies at the tower base.

Our construction crew on Red Mountain is quick to spot a
brush fire in Rainbow, just a few miles away, and the incident is relayed
to fire officials using amateur radio as the first communications
link. Soon, San Diego County Fire Helicopter #2 arrives on the scene and
prepares to siphon water from the Red Mountain reservoir to help extinguish
the blaze.

The CDF tower is rigged with ropes and a pulley in
preparation to lift FARC's two antennas (VHF & UHF) into place. Here, a
goodie bag is attached to the line to send supplies to the tower climbers
above. Pictured left to right: AA4CD, AC6X, W6DBM.

|
The VHF antenna is lifted, with the top and bottom of the
mast secured so it won't collide with the tapering tower structure. The
UHF antenna is later lifted the same way. Pictured left to right: AC6X,
AA4CD, W6DBM.

The VHF antenna in jockeyed into place between two CDF
antennas by KE6PCV (top) and WD6AHX. Note the super nice work platforms
provided. Our antenna really isn't pink, by the way. The color is just a
camera artifact.

KE6PCV and WD6AHX thread a coaxial jumper cable.
|
With outdoor antenna work underway, N3IZN and KG6HSQ install
the VHF and UHF coaxial runs indoors.
|
|
This photo shows the "wall penetration panel" where coaxial
lines enter the CDF equipment building. The silver boxes on FARC's coaxial
lines are lightning surge protectors. The black wires ground the protectors.

The FARC tower rigging and electrical crew, from left to
right, consists of Chris Durso (AA4CD) from Carlsbad, Dana McRae (W6DBM)
from Mammoth Lakes, George Rocheleau (AC6X) from Westminster, Ron Patten
(KG6HSQ) from Fallbrook, Marshall Oldham (KE6PCV) from Corona, Chris Arnold
(N3IZN) from Fallbrook, and Wayne Dewey (WD6AHX) from Carlsbad. Not
pictured: Bob Morrow (WB6DIJ) and Bob Gonsett (W6VR), both from
Fallbrook. All labor and many parts were donated, and very much appreciated!
