OK2A
- Marconi Memorial Contest 2018 from JO60LJ
Sorry for poor
Google translation from Czech
This year we tried to
get MMC from the Ore Mountains again. Without preparation, light. Only 2
operators, 2 antennas, 2 amplifiers and the necessary two-person support.
We spent two days and two nights there, and while we were in the rankings
a lot behind, we were twice satisfied. First of all, because the telegraph
traffic to VHF always pleases, and secondly because we have made a result
for which Klinovec does not need to be ashamed after time, and we got home
(despite the unpleasant mist) in good health and comfort and with
equipment, which has suffered no harm. So, after all, it was a nice
weekend.
However, the start of the
contest was not so pleasant. When Matej assembled the gear, PTT did not
work for PA Tajfun, even though we switched the PTT input with the
corresponding switching transistor in the driver. In the meantime, the
contest ran as a contest. I have tried different PTT connections but a
suitable shorting relay for PA keying (otherwise PA did not switch) a lime
tree man does not cut ... Well, after the first hour of the contest a
device (according to OK1TEH in a pre-tested assembly ...) to move around
because of such a perimeter nasty solution, which I will not boast here.
However, it has been shown that the RF from local FM and TV transmitters,
which dozens of kW burns within us from a distance of only a few tens of
meters. Eventually we managed to tame it too, but in the meantime our
competitors ran about one hundred QSO, so the start of the race was not
very nice. But finally, we're already on air!
We find out what is on the
bandwidth of disturbance - it probably leads noise from the Ethernet
cables to the microwave link on the nearest lattice tower, eliminating the
reception from the direction to S5 and 9A. Bold splatters is produced by
DJ2NR, and the OK7O phase noise is heard as well as, and far beyond them
is the OL7C nearest station. It can be seen that OK1UBO has done a good
job. Then on our side there was nothing interesting from my point of view.
Because of the delay, we are just looking at the far back of our
opponents, pouring gasoline into the motorgenerators, and knocking the
Italian antenna out of the hanging droplets of water, because almost to
Sunday afternoon we are in the clouds from which it is tiny and the
droplets of water stick to everything ... By the mutual effort of both
operators are finally approaching a couple of competitors, and so
ultimately, they are quite satisfied. It is a pity that the race did not
last for a few hours. But let's say the word to the operators who deserve
the result. I will be happy when we can sometimes win a race without
similar, though relatively small, but to upset rich hardware problems, hi.

Láďa OK1DIX:
I like CW racing and so when Matěj OK1TEH
came with the idea to go this year's MMC from Klinovec, so I agreed. The
weather forecast seemed to be quite good, and my XYL Majka OK1DYX was
willing to take this trip with us. So I tested the basic 2m TRX K3S with
the old TRV Sitno, including crystal filters. Matěj wanted to go in two
directions and so I was tasked to get another suitable power plant. It
turned out to be not an easy task. Due to the very fast changing load
during operation, it must be with the inverter. However, renting small
chips is not a very lucrative item. Most companies focus on large backup
systems. Finally, I succeeded in the company Kipor in Běchovice. Their
inverter IG2600 is exactly what we needed, and it worked great. I went to
OK1RK for PA Tajfun and my parts were completed.
On Friday in the evening we loaded a 10-el.Y. antenna DK7ZB from storage
and set off for our little house in Spaleniště. Immediately we melted the
stove. However, the temperature was at 1000 meters and at night around 5°C
and unlike Prague in the western Ore Mountains did not rain, so comfort.
Later OK1VPZ and OK1TEH arrived with caravan and second part of the
facility.
On Saturday morning we head to Klinovec. The weather is a little bit worse
than predicting, the clouds are rolling over the hills, but it does not
rain and is warm enough for November.
On the other hand, it does not attract so many people for trips and so we
can calmly dump the pins and build. We erected two masts 10m with 10 el.
DK7ZB and 7m with 8 el. I0JXX. Then comes the construction of a device
that makes OK1TEH. It takes a while, so the others will have lunch. After
the RX was launched, we want to re-adjust directions of the antennas and
it's a good idea. Plastic board on which the anchors do not rotate in the
smaller mast. There is no waste, the mast goes down. We find that due to
over-tightened screws, an aluminum tube around the plastic broken rotate.
We temporarily repair and the mast goes up again. But then a more serious
problem will emerge. PA Tajfun does not switch to tx by PTT. The box Matěj
prepared for keying two PAs, but somehow does not work. The problem is
that Tajfun wants a really short connection to ground and that bipolar
transistor on the PTT output from the driver can not. OK1VPZ is looking
for a solution. He's trying to get a small relay, but there's not enough
electricity to operate it. This would mean partially breaking up the
assembly and opening the exciter. After other inexperienced attempts and
the development of various combinations, we finally find a shoemaker
solution using a transistor and a parallel trimmer. However, the race is
probably lost.
I'm sitting on the righ, and I'm doing the first link right at 1500 UTC.
The band is quite dense. After several connections, I find strong
interference from DJ2NR splatters. It's about 80 km away from us, but it's
disturbing as if it was around the corner. The second unpleasant fact is
that the old TRV Sitno sometimes does not manage it in the kW environment
from the local commercial transmitters and depending on the rotation of
the antenna, generates cross modulation. The data from the nearby
telecommunication tower is also shuffling. There is no honey in this
environment, and I have to keep repeating more often than it is. In the
first hour there is nothing very unusual, but we will be pleased after 25
minutes by our famous Richard, G4CDN with a nice signal. Otherwise, most
DLs are OK and OK or PA there. In the next hour, Ivan, YU1LA and YU7ACO
appear to remain ODX for a long time. JV opens somewhat, thus increasing
the proportion of OM, 9A and HA stations. In the meantime, Matěj has
broken troubles the internet and is in charge of chat stations. And so
there are stations from I like I5MZY / 4, IQ6AN, IK4ZHH or IQ8BI from
JN63. In addition to interference and crosswords, however, there is
another difficulty. Clouds are condensed with water that does not make a
good antenna IOJXX. The water is tuning it and throwing it down SWR
protection PA. He must climb out about 3-4 times per hour, shake the mast
and knock water drops. I'm going with short breaks for food and a break
until about 2230 UTC. Then we leave with Majka at Spáleniště and leave
OK1TEH with OK1VPZ at night.
In the morning we come to Klinovec around 0800 UTC due to a problem with
the door at the cottage. Matěj, however, did not swim at night and in the
morning and made about 160 nice connections, with SM6BFE (new ODX 924 km)
and SM6VTZ (894 km). Also, the usual G3XDY and many nice QSOs came in I,
HB and F. There is also a larger number of OM, 9A and HA. YO2GL (805 km)
and YU1EM (837 km) were also held. Again, I accept the scepter. The
weather is getting better. We climb above the clouds and sun rises. The
antenna no longer needs to be knocked and the conditions improve mainly in
the direction of W and SW. Matěj again matches the chat. Interference from
DJ2NR is less, but there is noise from OK7O. The biggest problem is still
the crossword puzzle, but overall, the situation is somewhat better than
on Saturday. There are other nice stations like YT1WV (877 km) and YU7ON
(802 km), then our famous Maurice, F6DKW (796 km) and again several
stations. It is, after all, the Marconi Memorial Contest. During the
morning we alternate with Matthew, who wants to make a connection with
LA0BY. He tries it a couple of times, he spends enough time, but even if
he hears us there, we interfere with him sometimes, and he's not a QSO. At
the end of the race conditions are still improving on SW and so do F and
HB stations. The top and final ODX is the F6DRO of JN03 1159 km, which was
not even skittish.
The race ends with 490 valid QSOs and 181 ths. points. The light assembly
I had (18 elements in total and about 1400 W) is not bad, but not for the
lost hours at the beginning and quite a lot of interference, we could
think even higher.
Composition takes place in beautiful weather, the sun is shining, and
below is the sea of clouds. Matěj fascinatedly photographed panoramas and
awaits the sunset into the clouds. It is composed of an hour and
something. We are still enjoying and going with Majka towards Prague. In
spite of problems, eventually a great CW race, especially on Sunday.

Matěj OK1TEH:
Although we do not like the
"megalomaniac" two meter at our club, the Marconi memorial contest is our
favorite contest due to the telegraph and because we wanted the weather
forecast (ie it was not freezing and the rain was supposed to replace the
sun), we decided to try again after a long time MMC from Klinovec hill.
This QTH has its big plus and minus (especially the interference, the
harsh November weather at 1244m and the absence of usable electrical
connections), but it is still a famous hill with a long tradition of VHF
traffic, which is just 10km from our house in JO60JJ. MMC2018 was already
in the club for us in the fourth telegraph race from Klinovec.
The plan was clear, leaving a cool telegraph contest so that we could
enjoy as much fun as possible with as little effort as possible. That's
why we did not build any crazy multistands as usual for 2m and other clubs
to do then 200 QSO only, but we built only 2 simple Yagi-Uda antennas so
we did not even need to carry the antennas on the car roof and build them
was a question less than hours.
We went to Ore Mountains on Friday after job. 270km the caravan ride took
place without any problems, except that when crossing the Central
Mountains, we met under the hill Číčov at the village of Hořenec first by
the cops, who loaded a car with about 300kg of a 2m long monstrous wild
pig and about 1km further on the roadside came to greet a huge the twelfth
is just like advertising on the Jägermeister. On the hill, Lada and Majka
were waiting for us at the hot stones, and they could we are happy to say
that the October Brigade, with the laying of a new roof patches and
rubber-roof on the roof, made sense because it does not bother us into the
cottage.
In the morning we arrived to Klinovec and started to build antennas and
shack. By the way - tnx Láďa for securing the inverter generator to the
second direction. We were soon built in 4 people, so while I was wiring
the equipment, the others could go to a nearby pub for lunch. However, we
were a bit confused that we did not test the HW at home in full engagement
because there was an unexpected PTT problem for both PAs, which
unfortunately happened to shift the start of racing by 1h. There was also
a problem with the LTE router, who refused to connect to LTE, which, as I
discovered after the race, was a problem for the GoMobile operator, who
some-how erased our 4G activation for the new month. At the race, we were
only reliant on GPRS and therefore only ON4KST without the ability to
track aircraft via SW Airscout.
However, the late start of the race brought Lada a nice telegraph pile up
so the log grew happily with new connections. Compared to the previous MMC
in 2014 and 2011, he went smoothly to France, but we only did a
below-average QSO in PA, and we seemed to be weaker this time with
activity from the Balkans. Throughout Saturday until Sunday afternoon, we
were in dense clouds that rained slightly, which did not show the
narrowband I0JXX that we had every 20 minutes to knock. Around 10 pm Lada
and Majka left to sleep at the barracks, leaving me about next 10 hours of
traffic and a logistics "tankstelle" supporting VPZ. Outside of the dense
wet mist from the clouds, about + 2°C, and in wind gusts out there was not
much, but fortunately for these cases we drive in the caravan gas heater
and so we were good again soon.
Around 8am UTC, I was already catching "cartilage" and "crossword" did not
add my telegraph skills, but still I managed to make some nice QSOs over
800km to the SM over the metal roof of the hotel, such as SM6CEN, SM6VTZ
and finally SM6BFE 924km. Unfortunately, despite repeated attempts,
Stephan, LA0BY, did not succeed. Although I have heard him sometimes, but
the signal was too weak and the level unstable. Recapitulation, from 22UTC
to 8UTC nonstop operation, I managed to do 165 QSO, more than this time
could be made there by anyone else I think.
Then, with Lada in the morning, we changed shack by our taste a few times,
and I managed to do it among other things through the SP4K 10m tall roof
of the hotel 645km and the T7 / I4GHG also came. Around the afternoon the
clouds broke and we got over the inversion. At noon I leave the paddle
definitively to Lada and go out to make some nice photos from the lookout
tower. In addition, the internet connection is definitely leaving, so
there is not much to do in the caravan. Lada, meanwhile, praises a nice
QSO with the House, the F6DRO near the Pyrenees, which is ODX's final
1159km, a pity that the race did not last for an hour longer.
The final score of 181 240 points and 490 valid QSOs we consider as nice
and we are only a little bit sorry that it could have been a little better
due to the initial wasting hour as OK competitors did not have a
head-to-head advantage, but as it sings in one of the famous rock songs "
it 's just rock 'n' roll, so maybe the next time. Our reward was to invoke
the magical sunset when we packed it, then take the 270km with the
caravan, take the car from the car to the dome on the stairs, and after
about 2am in the morning we could go to sleep with a feeling of good work.
Finally, a few words about QRM. Subjectively, with some exceptions, we had
no big problems with anyone, and surprisingly not with the local OL7C.
From which we have always tried to go beyond the width of the IF crystal
filter. It is worth mentioning the relatively bad / wide OK7O signal that
contained the hum and we also had a problem with the OL3Y in a situation
where we had the antennas turned against each other. Unsurprisingly the
worst was the DJ2NR signal, which went from QTH DL6NAA, who just
celebrated the birth of a congrats during the contest. I also have to
mention the signal from the OM5ZW, which on those 409 km burst the
incredible S9 + 40dB on the sweep and was significantly stronger than
OM3KII or OM6A. I almost had the feeling that the transmitter was
somewhere beyond the corner.
In summary, our team is again satisfied and I think it was a dignified end
of the racing season.
Thanks to all who gave us points and we hope hear you of the Ore Mountains
in 2019 again
Matěj, OK1TEH
