The 1999 WPX followed the usual pattern for a WPX from VK4 - working into
the side of every Yagi in the northern hemisphere. My thanks to all those
who took the time to turn their beam our way.
Early preparation efforts suffered the usual problems of commitments to
family and work and a proposed multi multi effort became a Multi Single
effort before the contest had started.
We all gathered at the QTH of Kerry VK4MZ, at Gympie, 175kms north of
Brisbane, on Friday morning, 24 hours before the contest. Friday was spent
preparing the computer equipment and running cables. On the RF side, it
was simply a matter of connecting the coax and installing the listening post
Most of the computer equipment was under test, in preparation for a multi
multi effort later in the year. Three types of network topology were being
tested: Ethernet using COAX and UTP, and a very long run of serial cable.
In the early hours of the contest it was difficult to break into the
triangle of Europe, USA, and Japan. We failed to secure a run frequency on
10, or 15 meters, until 40 meters opened at 0820z. This was to affect our
activity for the rest of the weekend as we struggled to catch up.
40m was our best chance, and, though slow at times on the first night, we
worked 40 meters to the US, Japan, and Europe, all through the dark hours
until 2000z. 10 meters then opened into the USA, and we worked solid rates
until California faded at around 0200z. Switching to 15m and working long
path towards Europe, dropping to 20 meters at 0445z, we were surprised by
the number of South American stations working the contest.
We tried 40 meters at 0630z, but it proved too early to get a run going.
We ran Europeans long path on 20 meters until 0730z when we again used our
best equipment to work 40 meters into the US. The usual short opening on 10
and 15 meters at 0900z into Europe was worked, with a return to 40 meters
at 1115z. 40 meter band conditions was not as good as the previous night
and we ran 20 meters into Europe from 1300z to 2000z.
In the final hours of the contest, the 10 meter band conditions seemed good
for us, but few operators seemed to be on the air. We worked strong
stations into the US, but new contacts were few and far between. We worked
several VKs during this period all having the same problems. On the
positive side, we had a good "chat" with some US operators, working W0ZZ
The CT software performed well. We experienced two problems: The band map
ceased to update over the network from the listening post at one point, but
a reload of all computers cured the problem; In the final hours the run
station could not select spots from the band map. The cursor jumped
randomly around the band map. We worked around the problem by reading the
band map and entering the frequency and call manually.
The network topology worked flawlessly in a network of 5 computers
(run station, listening post, "spare", "kitchen" monitor, network packet
monitor) to test RF immunity for future multi multi efforts. The UTP hub
and cabling operated without any problems from RF, and the "long haul"
survived without problems - all logs were in sync at the end of 48 hours.
The biggest surprise of the whole contest was the lack of JAs on 10 and 15
meters. We worked most multipliers on 20 meters into Europe both short and
long path. Clearly, we need to do more to break into the European wall of
QRM and make ourselves heard.
The lynch pin of our efforts was the performance of VK4MZ's equipment on 40
meters. This, combined with the operating experience of Kerry VK4MZ and
George VK4XY gave us 512 high scoring QSOs with 173 multipliers. John
VK4CEJ worked any band with skill, and Bernard DL2GAC provided valuable
assistance on the "listening post". My thanks to them all.
Until next year ...
