Under arrangement of our
friends from OK1KIM, Ivo, OK1FRI and Zdeno,
OK1DFC, we were invited by Hilversum club station to the UHF/SHF contest. The
contest QTH was prepared in the boy-scout cottage near Hilversum. We met at the
place the night before the contest . Fortunately, because of the darkness we
could not see anything around. In the morning we were simply shocked, but it was
too late to return back to our regular contest place in Czech Republic. We were
in a small backyard. There was a highway on the 8 - 10 m high rampart to the
east and a very high voltage line (1000 kV ! AC) on the opposite side. When we
errected our mast, the antenna was almost at the same level as motorway surface.
Moving trucks made a very deep QSB !
Nevertheless we started the contest in time. Because OK2KKW is a club station
call sign and we didn't make any arrangement with the Holland authorities, we
had to use the private call sign of Franta, OK1WC. Our Holland friends were
surprised by our equipment, especially by the output power (750 W on 70 cm) and
told us they never made more than 140 QSOs on 70 cm there. The very bad QTH
affected our result very much. Nevertheless we could make a couple of QSOs to
Czechoslovakia, but there were permanent problems with QRN from the high voltage
line. We had also a litte contoversy with one known Holland ham. His house was
located only few kilometers from our QTH (JO22OF) and he was concerned about our
signal strength. His alleged us of having bad signal quality, because his
Philips spectrum analyzer showed our signals 400 kHz wide. He did not accept my
explanation, that any spectrum analyzer doesn't have the purity of the local
oscillator good enough to dectect side phase noise of the oscillator of TRX. He
answered he had Philips equipment and nobody could made anything better…We could
even show him that his signals interferred on our RX in the same manner as our
signals on his and offered him checking both signal on another RX, but he did
not care. We were disappointed by his opinion, but no one can overtake physical
laws. On the other hand he is no doubt a brilliant microwave ham and he made a
great job in the popularization of 10 GHz band among European hams.
Concerning results we might have taken 3rd place in multi 70 cm category, behind
PA0PLY and PA6C. We don't have any confirmation of that, because we didn't
receive any official results from Veron organisation.
Another surprises for our Holland friends were:
- we were using a laptop computer for logging during the contest
- our Skoda cars needed unleaded gas
- I was able (because I am sensitive for it) to find water or water pipe or
underground electrical cable using a piece of wire or a tree branch...
