The ZX0F Story - CQWW SSB 1999 Multi Multi Operation
by Atilano de Oms Sobrinho - PY5EG
Initial Planning - The Stage is Set=20
A major multi-transmitter/multi-operator entry during the 1999 CQWW SSB
Comp=
etition has just been completed from the Brazilian Island of Fernando de
Nor=
onha under the special callsign ZX0F. =20
Led by Atilano de Oms, PY5EG, and organized under the banner of the
Araucari=
a Dx Group of Parana, Brazil, and with a great support from the
Bulgarian te=
am, an International crew of (12) contesters from Brazil, the USA,
Bulgaria =
and the UK began arriving on the island in late October in order to
particip=
ate in the contest from 29-31 October 1999. =20
Members of the team included:

David - Telecommunciations
Nicolau - HF Antenna Rigging
Andre (PY0FF) - Our Host and Facilities Provider
A few special words need to be said about our host for this operation.
Our =
host was Andre Sampaio, PY0FF, and the operation was conducted from
Andre's =
lovely bed and breakfast known locally as the "Pousada de Morena" on
Fernan=
do de Noronha. While Andre did not operate or specifically work with
the te=
am during the contest, it would never have taken place without his
friendshi=
p and full support.
The idea for this operation was originally conceived at the Dayton
Hamventio=
n in May 1999 when Krassi (K1LZ) and Oms (PY5EG) met and agreed to make
a se=
rious attempt in CQWW SSB using (6) six new ACOM auto-tune amplifiers
for th=
e operation. Krassi wanted a chance to test the performance of his new
ampl=
ifier line and Oms wanted to see how competitive an International score
coul=
d be made in the highly competitive multi-multi class from a deep South
Amer=
ican location.
=20
By way of background, the Arauc=E1ria DX Group had already achieved
several =
records in both the WPX and CQWW contests operating in the Single band,
Sing=
le-Op allband, and Multi-single categories from the existing contest
station=
s of the Group. One is normally operated with the call sign ZW5B from
the P=
Y5EG home-QTH , the newest one is been operated with the call ZX5J from
"Boa=
Vista Mountain" near Florianopolis Sta. Catarina. In Fernando de
Noronha I=
sland, the very well known Araucaria Dx Group has also built up a very
compe=
titive contest station normally operated with the special callsign ZX0F.
The=
property is quite small and does not have sufficient space for a true
multi=
-multi effort. Actually, it is better suited for multi-single,
single-op al=
l band or single band operations.
Even considering these limitations, the Group decided to go for a
multi-mult=
i effort with the main objective of learning some of the most important
tech=
niques for such operation, and also to enlarge the know-how for a big
future=
project. The idea is to build a contest station specifically dedicated
to t=
he multi-multi category.=20
During the summer and early fall, intensive preparations were made and
the g=
roup used email and the Internet to finalize arrangements. Logistical
plann=
ing was an enormous task and included many advance shipments to the
island. =
These included the Acom amplifiers, thousands of meters of coaxial
cable an=
d wire for the antennas as well as helium gas for supporting various
lowband=
wire antennas. The experts in software also worked very hard to learn
and a=
dapt CT to DXTELNET, and how to put both on a reliable communications
networ=
k for use in a contest.=20
The plan was to run with stacked monoband yagis for 20, 15 and 10
meters, tw=
o monoband yagis for 40 meters and wire beams/verticals for the lowbands
80 =
and 160M. Phased beverages would be employed in order to optimize
reception=
on 80 and 160m.
One of the biggest challenges was to solve the problem of intra-station
inte=
rference between the stations due the congestion of antennas on a small
piec=
e of land. Nick, LZ1JY, and Krassy, K1LZ, did an extremely efficient
job on=
this matter. It was amazing how they reduced the level of interference
to =
a minimum in such a small place.=20
Additionally, the group would optimize its multiplier search efforts by
acce=
ssing several overseas Dx packet clusters in the USA and Europe using
the K1=
XX gateway in NH and the well-known Dx Telnet software.
Arrival on the Island
N5FA (Jim) and PY5CC (Peter) were first to arrive on the island on the
20th =
of October along with Nicolau, a trusted friend of PY5EG, who was the
group'=
s most experienced tower rigger on the team. Although not an amateur,
Nicol=
au sure knows his way around towers and was very skilled in maneuvering
huge=
monoband yagis with 15 meter long boomlengths. He and Peter made it
look e=
asy - although we knew it was not!
While Peter and Nicolau worked optimizing the yagis, Jim, N5FA, set
about st=
ringing wire down to the beach through the jungle for the various
beverage R=
X systems.
On the 26th of October, members of the US and Bulgarian teams arrived
includ=
ing K1ZM, K1CC, K2DM and K1LZ. (Fortunately for the team, our
telecommunica=
tions expert, David, who is not an amateur but, rather, an employee of
Inepa=
r, Br who works for Oms also arrived this day to help with CT and
network pr=
eparations. We soon learned that David was **damn good** and without
him we=
would not have kept our network working for very long. It seemed he
was ev=
erywhere before and during the contest making sure all the computers
stayed =
up and on-line).
Due to a very congested business schedule, PY5EG Oms, PY5ZBU Don and
PY5GU G=
us, arrived on the Island only late Wednesday.=20
The group by now had divided itself into teams:
Station Setup team
Lowband Beverage Team
Network Team
Highband Antenna Team
A/C Power Hookup Team
Station Interference Minimization Team
Work proceeded almost 24 hours a day for the next three days until
finally t=
he crew was ready to go for the start of the contest. Only short breaks
wer=
e taken for a minimum of sleep and for the taking of meals in Andre's
very f=
ine Italian restaurant - the finest on the island.
0001Z 30 October - The Race is ON!
With several exceptions, the group shared operating responsibilities and
mos=
t operators got to operate on ALL the various bands at one time or
another. =
Oms specialized on 40M SSB and operated the first night on that
difficult b=
and making around 1000 Qs, but other ops on the team also got to try
their h=
and on 7Mhz on the second day as well. Everyone got the chance to
experienc=
e the high QSO rates possible using a rare call sign from a rare country
- i=
ncluding our developing younger operators on the team. That's what
contesti=
ng is all about - trying to bring along new blood into the hobby and
then te=
aching them how to operate successfully in a major competition. We feel
we =
did a good job with this part of the operation.
As the contest progressed, rates peaked over 250 contacts per hour at
severa=
l times on the individual higher bands and the overall CT rate meter
peaked =
at nearly 1000 a number of times during the best European runs on the
higher=
bands at sunrise on Saturday morning.
At the end of the first 24 hours we had 11000 QSOs and we felt that we
could=
reach the 20,000 target Qs we had set for ourselves at the start of the
com=
petition. But, we were totally wrong. During all the afternoon of the
secon=
d day and portions of the night we had a propagation cloud over us on
all ba=
nds and the rate dropped to a very low mark. On the second day we made
only=
56% of the Qs of the previous day!!!.
When it was all over, the group was generally pleased with a solid score
out=
come of over 50 Million points - the highest score ever made from deep
South=
America. While it is somewhat disappointing not to *win* the contest
outri=
ght, each team member recognized the geographical distances involved
between=
PY0F and the USA and Europe - knowing that teams like IG9A, CN8WW and
PJ4B =
were more favored operating locations. Considering our distance from
Europe=
especially, we were very pleased with our results.
Our CLAIMED SCORE breakdown is as follows:
BAND QSO QSO PTS PTS/QSO ZONES COUNTRIES
160 260 754 2.90 17 56
80 806 2338 2.90 28 97

Aftermath
On Monday, the troops began scattering as soon as a ZX0F group picture
was t=
aken with the ACOM amps in front and El Pico in the background. Pico is
a 3=
00m tall rock outcropping that defines the island from a distance and
lies j=
ust to the West of the shot from ZX0F towards the USA.
K1ZM, K2DM, K1LZ, K1CC, LZ1JK and LZ1JY hung around the island just long
eno=
ugh to go touring on Tuesday after all the lowband antennas had been
disasse=
mbled. The group enjoyed snorkeling with the dolphins and cruising the
Nort=
h side of the island most of the afternoon.
Like all good things, this operation had come to an end and the last of
the =
team said it's good-byes to Andre at Noon at the airport on Wednesday, 3
Nov=
ember. This gave Andre, PY0FF, some much-needed "peace" on his lovely
islan=
d and a chance to put his bed and breakfast back in some semblance of
order =
following the wild events of the preceding two weeks!
Where Do We Go from Here?
Well, it is hard to say for sure. But, the team felt a definite kinship
(br=
otherhood) among the group and will consider another effort at a point
in th=
e future - possibly for CQWPX SSB in March 2000. This may be attempted
as a=
Multi-Single or Multi-Multi either at ZX5J in Santa Catarina or at Oms'
hom=
e station at ZW5B in Curitiba, or even another operation from ZX0F.
Many thanks to all of those who worked us. It was our pleasure
operating at=
ZX0F and we hope to see you from the next operation. Qsl's for the
ZX0F op=
eration are via PY5EG.
Our best thanks also to, ACOM, DXTELNET, CT(K1EA Software), WX0B (ARRAY
SOLU=
TIONS), and especially to K1XX for the extraordinary support with our
packe=
tcluster link.
What we will always remember - our best results of the contest:
1) The contest family we formed (Bulgaria+USA+Brazil+UK) fantastic!.
2) Effective solutions to station interference elimination (Thanks
LZ1JY+K=
1ZM+K1LZ)
3) Computer network (Thanks to David + Krassy + K1TTT + K1XX)
4) Low band reception beverages (Thanks to N5FA + K1ZM)
5) Multiplier passing (Thanks to N5FA )
6) How to build up antennas in a small area efficiently (thanks to PY5CC
and=
Nicolau)
7) How to keep our equipment running (Thanks to LZ1JK+PY5ZBU)
8) Hospitality (Thanks to Andre & Morena)
Thanks also to God for this Gift!!!!
73 and hope to CU in the next one,
Oms - PY5EG
