The HC8N Experience
by Don Field G3XTT
There cannot be many active amateurs who are missing HC8A or HC8N from
their log. Over the past ten years or so, the HC8N call alone has
accounted for something like 320,000 QSOs on all bands and modes, let
alone those made by HC8A (N6KT), HC8L (W6NL) and others. What’s the
story? As it happens, I have known Trey N5KO (ex-WN4KKN), one of the
key players, since January 1991 when we first met at a Northern
California Contest Club meeting. I have been able to follow the
development of what has become one of the world’s “super
stations” in the following years and, recently, was able to achieve
an ambition to participate in one of the operations, specifically
their CQWW CW at the end of November.
Some History
Over the years HC8 has been a magnet for amateur radio operations,
both expeditions and contest operations. It has many
advantages. Propagation is excellent, with its equatorial location,
and favourable take-off especially to the USA (it lies directly south
of W5). In major contests it is a rare multiplier, often a double
multiplier (CP, HC and OA are also in zone 10, but with relatively
little activity). And it is easy to reach and, by developing-world
standards, benefits from a good infrastructure. Last but by no means
least, is that there is on-site assistance from Guido HC8GR, who you
will now be familiar with from G4IUF’s article elsewhere in this
Digest (p.xxx).
In the 1980’s Rick Dorsch NE8Z lived and worked in Ecuador and made
several forays to HC8. Rick obviously made contact with Guido HC8GR,
and this led to a number of Rick’s US-based friends heading to HC8,
particularly for contest operations. Especially relevant to our story
are Rich Smith N6KT, one of the world’s finest SSB contesters, who
soon had his own HC8 callsign, HC8A. On the CW side Trey, N5KO, got
himself the call HC8N and started to settle on HC8 as a tried and
trusted contest location having, for several years, led a peripatetic
contest existence, acting as guest-op from TI, ZP, PY and other
locations.
Some early HC8 operations took place from a farm owned by Guido’s
family on the highlands of San Cristobal. It was apparent that the
take-off from that location was excellent, and there were several
successful efforts from there including one by N6ZZ, W6NV and others
in the late 80s. By the time the farm was sold, there were 3 permanent
towers, which then formed the basis of subsequent contest operations
from Guido’s house.
Back then, in the early 90s, the town was somewhat less developed than
now, and a good deal of land adjacent to Guido’s QTH was
undeveloped. Visiting contesters were able to spread into this land
for antennas, to the point where the QTH eventually sported four
towers ranging from 40 to 70ft in height (using some of the towers
removed from the farm), with a variety of monoband Yagis.
El Junco is born
This state of affairs lasted for several years, with some fine contest
scores being posted from HC8. However, to cut a long story short,
problems with power-line noise and gradual encroachment by building
development, meant that, while Guido’s home continued to be a fine
base for the more casual holiday-style operations such as that made by
G4IUF, it was increasingly unsuitable for major contest efforts.
Thus it was that when an parcel of land close to the old farm site
became available, Rich N6KT, Trey N5KO, and Dave W6NL (ex-W6QHS and
technical guru including being author of the popular book Physical
Design of Yagi Antennas), decided to take the plunge and build a
permanent contest QTH on what is probably the best radio location on
the island (which I’ll refer to from hereon as El Junco, named after
the island’s extinct volcano, whose crater is just a half-mile or so
away).
First Activities
The first operations from El Junco took place in the autumn of 1998,
still almost field-day style. The QTH had been bought as a virgin plot
of land, and it had been necessary to bring in a spur from the
island’s electricity supply and to break ground on a house which would
serve as operating location and accommodation for visiting
operators. At the same time, the four towers which had been used
previously at Guido’s QTH, were relocated to El Junco, and set up with
enough antennas to be able to mount a reasonable scale of
operation. Nevertheless, when the initial activities took place the
house was only partially completed and open, at least to some extent,
to the elements. As a result, CQWW RTTY (September 1998) and CQWW
Phone (October 1998) were operated from a tent, while CQWW CW
(November 1998) was from the partially-completed house. It’s perhaps
worth mentioning “the elements” at this point. The climate at
sea level in the Galapagos is extremely pleasant, with high
temperatures and plenty of sunshine, but moderated by sea breezes.
However, on the mountainous islands (and several of the HC8 islands
fall into this category), the mountain peaks tend to be covered in
cloud for around eight months of the year. El Junco is at
600m. Temperatures are typically 20 degrees Fahrenheit lower than at
sea level, and the air is damp (and that’s when it’s not actually
raining). Visibility is also limited; for much of the time I was there
in November we were unable to see all four of the towers from the
house. At times we couldn’t see any of them. But it soon became clear
that, from a radio point of view, the site is excellent. The ground
falls away rapidly towards the sea in the main directions of Europe
(across Eastern USA) and Japan (across Western USA), and signals to
and from those locations are invariably excellent on all bands.
I am astonished at what the three protagonists have achieved since
that 1998 start, assisted of course by a huge amount of local effort
from Guido and regular assistance from visiting operators. Little has
appeared in print, but it is worth digging out the QST article (April
2002) which, although dealing with El Junco mainly from a 6-metre
perspective, gives a flavour of the place, along with some excellent
photographs.
The current El Junco station sports four 135 ft towers, each focused
on an HF band and, between them, supporting antennas for LF. There is
also an inverted-vee, at about 100ft, for 30m and, recently-installed,
a pair of duo-band 12/17 metre Yagis (Force 12) fixed on JA and
EU. Behind the house is a smaller tower carrying a C3 tribander and a
7-element 6-metre Yagi. The antenna complement is shown in the
table. The antennas are roughly 50/50 Force-12 and W6NL homebrew. Of
particular interest is the 3-element 40, which was designed and built
by W6NL, and brought to HC8 in a ski-bag!

Inside the station, a huge amount of equipment has been accumulated
over the years, although for most operations it is necessary to bring
in the main radios. All feeders are terminated at WX0B switching
boxes. However, there is no permanent station set-up, as the
requirements of each contest tend to be different, and the station has
been used for single-op, multi-single, multi-two and multi-multi at
various times. This means that the stations and the logging network
usually have to be set up from scratch. And, of course, visiting
operators are encouraged to activate HC8 outside the contest, often on
the WARC bands or specialist modes, which requires further
reconfiguration of antennas, bandpass filters, etc. To give you a
flavour, for this year’s CQWW CW, which was the focus of my trip, the
main station configuration was as per the table below. The top three
bands also had a second rig available for multiplier-spotting. A
PacketCluster link was established via the WARC bands (30 at night, 12
by day) with K5TR.

Which tales us nicely to this year’s contest. The plan was to operate
multi-multi, with ten operators who, for the first time, would include
visitors from Europe as well as the USA. The team consisted of:
| 10m: |
HA1AG K9NW |
| 15m: |
K1DG K6AW |
| 20m: |
S50A WA6O |
| 40m: |
K1EA N5KO |
| 80m: |
G3XTT |
| 160m: |
K5KA |
Obviously these were primary responsibilities, but with flexibility
according to who was available and which bands were open at any given
time.
Members of the team flew in by various routes, and at different
times. I was the last to arrive, having been constrained by arriving
back just days before from a holiday with my xyl. My own route was via
Miami to Quito, overnight in Quito and then on to San Cristobal. All
Galapagos flights originate in Quito with a stop in Guayaquil, and
vice versa on the return trip (Mike’s article also mentions this. The
reason for not leaving Quito with a full fuel load is to reduce weight
as Quito is almost 10,000 ft asl, surrounded by the Andes, making
take-off quite exciting!). On arrival in HC8 I was met by Guido HC8GR
and Tine S50A. Tine and his wife (S56MM) were staying at Guido’s; the
rest of the team were at El Junco. After a brief stop at Guido’s QTH
it was off across the island to El Junco, arriving in time to join the
rest of the team for lunch. It turned out that I had missed the
majority of the antenna work that had been needed, though I did get to
stand in the rain that afternoon, helping Trey to adjust the 80m wire
Yagi. I could hardly complain. While we were doing this Ken K5KA was
off up one of the towers to attach the new topband sloper, with Doug
K1DG walking the bottom end down the hill amongst some pretty
unpleasant foliage and terrain (Ken and Doug were barely able to spot
one another through the low cloud while undertaking this task!). By
arriving last I had missed the opportunity for a one-day boat trip to
see some of the local wildlife. Most of the team had done this, and
had stories of sea lions and turtles, but there were also some
unpleasant cases of sunburn from reflections off the sea.
Pre-Contest
The routine settled into completing station set-up and running the
occasional pile-up to get a feel for propagation and ensure that
everything was working OK. I was more then satisfied with results on
80m, although it did look as though the 80m wire Yagi was little
different to the European dipole when working EU or East Coast
US. Having K1EA as a team member added an element of amusement. I well
remember, years ago, the panic before each CQWW to ensure that we had
the very latest release of CT (at least once, received by FedEx from
the US just hours before taking the ferry to GU). But in HC8 we went
one better, by having three new releases generated on location, as Ken
took the opportunity to add new radio interfaces (IC-756 ProII, and
TS-930 PiEXX board) and test them in situ. Domestically, we were well
taken care of by the family which lives at El Junco as
caretakers. This couple (and their energetic 4 year-old daughter),
have done a tremendous amount to domesticate the site, and the meals
that they provide are just what hungry contesters need. Guido and his
family are also regular visitors, keeping an eye on the management of
the place. Incidentally, this might be the right time to mention, in
case any of you were wondering, that 97% of the land area of HC8 is a
designated National Park, while the remaining 3% is for habitation and
cultivation. Obviously the El Junco site falls within that 3%. It is a
little irritating that all visitors to HC8 have to pay a one-off
National Parks tax of $100, even if, like us, you never set foot
outside the 3% which falls outside the National Parks area. Anyway, at
least in doing so we were making some small contribution to the
maintenance of these islands as the unique ecosystem that they
are. Most of us also got the opportunity to visit the Darwin
Interpretation Centre, sponsored by Spain, which gives a fascinating
overview of the history and ecosystem of the islands.
The Contest
Typically, within minutes of the start of the contest, technical
problems started to emerge, despite having soak-tested everything over
the preceding days. The 15m station developed a switching fault which
kept it off the air for the first half-hour or so of the contest,
while the topband signal was definitely T6 or worse, a problem traced
to a drop in mains voltage which the outboard PSU couldn’t handle
(fixed by changing PSU). On the whole, though, things went pretty
smoothly, though K5KA and I found ourselves wrestling with a
relatively high ambient noise level on the LF bands. What I found
interesting, and unexpected, was that I had imagined 160 and 80 would
be wall-to-wall with loud US signals throughout the hours of
darkness. In fact this was far from being the case. I was able to work
through the pile on 80 in the first few hours, to the point where
frequent CQs were in order, and the loud Europeans had absolutely no
problem in getting through. I guess the North American stations are on
the high bands or it bed after about 0500 GMT, so European dawn is relatively free of W and VE QRM.
The new 160m sloper worked extremely well, but the propagation gods
simply didn’t co-operate. Just three UK stations made it on 160:
GU4YOX G4BUO and GW3TMP. Congratulations especially to Bob GU4YOX who
was not only the first UK station to get through, but did so with 50
watts from G4TSH’s old TS930! Oh to live by the sea on GU! The 80m log
records 42 UK QSOs: G0OPB G0ORH G3GAF G3GLL G3IGW G3JAG G3KZR G3LZQ
G3NAS G3SED G3SNN G3SWH G3TXF G3UFY G3VXJ G3WGV G3WUX G3XGC G3XYC
G3ZGC G4BUO G4DJX G4ELZ G4HXX G4IIY G4IRN G4KFT G4PWA G5LP GI3FJX GI5W
GJ2A GM0F GM3JKS GM3YOR GM4SID GM4YXI M2A M7M MM0BQI MU5X MW5A. Well
done one and all.
The high bands seemed to go well, with several QRP G stations making
easy QSOs with HC8N (Paul G0WAT logged us on three bands with 5 watts
to a multiband vertical). Those big monobanders at HC8N, along with
the excellent take-off and the benefit of equatorial propagation
certainly do the trick. In the event though, it seems we came in
second to the EA8ZS team, who benefited from a single-hop into Europe,
with lots of QSOs and country mults on the low bands that we and the
gang at XT2DX simply couldn’t match. But lots of fun was undoubtedly
had by all.

After the Contest
Not actually after the contest, in fact, but a few hours before it
finished we were visited by none other than Fernando EA8AK, someone I
have been working on 160 for almost 30 years but who I had never
met. Fernando is an MEP (Member of the European Parliament) for Spain,
and was in Ecuador/Galapagos to oversee the national elections on
behalf of the EC. Needless to say, the discussion quickly moved from
politics to topband!
The following day some of the operators had to make a hasty departure
to be back with their families for Thanksgiving. Those of us who
remained did a little sightseeing, plus spending more time on the
bands. As Mike observes in his article, the WARC bands have probably
been under-exploited from HC8, as most activity has been on the main
(contest) bands. I fired up one of the linears on 30, 17 and 12
(surprisingly, all WARC band activity to date from El Junco had been
barefoot), and had a great time running the pile-ups, with the two new
WARC-band antennas. Hopefully it will have given some a you some new
slots. Meanwhile Zoli HA1AG was determined to make his mark in a very
different way, and borrowed my laptop to make the very first SSTV QSOs
from HC8. He soon had what I understood to be the SSTV equivalent of a
pile-up, and put some tens of QSOs in the log. While this was
happening, Mike WA6O, who had taken the trouble to acquire his own HC8
call, was busily using it to make some noise, mainly on 20m. We also
had a “media” visit from the local TV station, who were
preparing a feature on our operation. Trey and Guido explained at
length (in Spanish, of course) what we were up to. Whether the TV
presenters managed to make any sense of these crazy hams and their
contest (“concurso”) is another matter!
The journey home was uneventful. As Mike says, Ecuador actually seems
like a haven of peace and tranquility, and Quito is a beautiful
city. The Spanish architecture in the “old town” area is quite
magnificent. Zoli HA1AG and I had a day to see the sights, and as well
as some visiting around the town we also headed out to La Mitad del
Mundo, where we took the standard tourist pictures, standing astride
the equator. This is where a famous French scientist fixed the
location of the equator, calculated the length of a kilometre (one
ten-thousandth of the distance from equator to pole if I recall
correctly) and showed that the earth is actually an oblate spheroid,
rather than perfectly round. Mind you, finding the equator can’t have
been too hard – there’s a bright yellow line painted there!
Last, but by no means least, my thanks to Trey for the invitation to
operate from HC8N, to Guido and his family, to Isidro, Lida and Jodi
at El Junco, to Janet for allowing me to go off on these jaunts, and
to my fellow operators for making the whole experience so enjoyable.
