W3SO is primarily a VHF contest station located 100 miles east of Pittsburgh in
grid FN00sn, ARRL WPA Section. It is on top of Wopsononock Mountain near
Altoona, Blair County, PA, in the Allegheny Mountains, at elevation 2500 feet.
The picture shows the W3SO operators for the September 2006 ARRL VHF contest.

Begining in 1996 with a portable operation using three push up towers, two
tents and the owners call W3YOZ, PVRC operators found the site to be a good one
for VHF communications. The group subsequently found the site to be good for
ARRL Sweepstakes, 160m contests, Field Day, and the PA QSO party. The
Wopsononock Mountaintop Operators got their own call, W3SO, in May 2000.
Two buildings house four VHF, several HF positions, and the following VHF/UHF
repeaters: W3QW 146.82 (-) PL 123 2m FM repeater, W3VO 444.600(+) PL 123 UHF FM
repeater, W3VO-1 144.93 APRS digipeater and W3VO-2 local packet digipeater on
145.01.
W3SO is a Limited Multiop station on VHF/UHF bands 50, 144, 222, 432 MHz. (QRGs
of 50.160, 144.220, 222.115, and 432.115 MHz.). Computers are networked for
passing. We currently use 486 computers with the CT logging program. Antennas
are a seven element C3i beam on 6m at 95 feet, stacked five element 6m C3i
beams at 72 and 90 feet, stacked 15 element C3i beams on 144 MHz at 82 and 95
feet, a Force-12 17 element 2m beam at 75 feet, a 22 element C3i beam on 222
MHz at 105 feet, and a 25 element C3i beam on 432 MHz at 93 feet. During
contests we use the 2m repeater Station Master vertical at 100 feet.
W3SO participates in the January, June and September ARRL VHF contests, the
July CQ World Wide VHF Contest, and in the spring and fall 50, 144, 222, and
432 MHz sprints.
Although the first two or three years were made possible by KA3EJJ and KC3EK
who were experienced VHFers and who provided temporary towers, loaned rotors
and antennas, the actual permanent station construction was done by HF
contesters new to VHF who viewed operating just four VHF bands as being
possible, but no more. Being in the Limited MultiOp category is like being a
triple A league baseball team, where the MultiOp stations are major league.
If there is anything remarkable about this station it is that it was put
together by hams entirely in their 60s. We do all of our own tower climbing,
tower assembly, guy manufacturing, guying, rotor and mast mounting, antenna and
feedline installation. Only the concrete work was done by others. There are
eight towers so far, a rate of almost one a year.
Being in a rare grid is a distinct advantage. Being in this one, FN00, means
you have to go a grid and a half before you can work anyone. Pittsburgh, EN90,
at 100 miles is the closest major populated area.
Everyone brings a different piece of gear. The first station bought equipment
were the DCI filters. We share this mountaintop with eighteen commercial towers
ranging from 150 to 400 feet in height. They support antennas for three TV
stations, a couple FM, fire, police, taxicab, state emergency, etc. Only in the
first year did we have a problem, on 222, with a paging system which was
discontinued.
Three pushup towers were followed by the first guyed tower and a 100 foot
crankup, followed by a second guyed tower with 6m and 222, tower #1 with 2m and
432 antennas. Several of these antennas were "housewarming" gifts of
K3CB, the K8GP sponsor.
It took until the third year to be able to do both the June and September
events. January would come later. Rigs older than 25 years and 100 watt bricks
were used. Only occasionally someone would bring a 222 setup. Scores were
around 50K or lower. The contest usually provided the only time a ground crew
was available for new antenna installation. Sometimes this didn't get done
until well after the contest started. It took years before we ever topped the
70K score from the very first year. All of the LMR feedlines were replaced at
the same time by 7/8 inch hardline. The scores doubled putting us over 100K for
the first time. We finally got in a top ten box at tenth place.
The third tower is unfinished at 100 feet, currently used for the four
repeaters. With completion af the fourth tower, 432, 2m and 6m were now
independent. The first ice storm destroyed the 2m and original 432 antennas on
tower #1 and bent the 6m on tower #2, causing us to miss that January. The 6m
was repaired and moved to a new tower #5, and a new 2m antenna placed on tower
#2. When we got the septic drain field dug the backhoe operator mistakenly
swung around and mercifully destroyed tower #1, enabling us to use his
insurance money to get a crane to take it down and replace it with a brand new
105 foot tower with an independent 222 antenna. Now, all four bands were
independent. The second ice storm broke the 2m antenna just weeks before a
January contest. Two subfreezing climbs to take down and put up a new one saved
that January.
The original loaner rotors were always breaking or freezing up in January. They
were replaced by Pro-Sis-Tel rotors. Bricks were replaced by KW amps. Preamps
were added for each band. The first stacked array was for 6m fixed to the
northeast, the second, a rotatable pair for 2m on a new tower #6.
Incrementally, these station improvements led to 3rd, 2nd and finally a 1st
place finish.
