Deja-vu with happy end

Here is DL0GTH's June contest report 2006 (by DL6AUI and DL2ALF) :
 

Everything started like one year ago :

Weather forecast promised cold fronts in a row for the contest weekend. We started loading the van on Friday as usual without rain. On Saturday we were quite in a hurry to complete the antenna setup before rain started.

But just arrived we had to celebrate Harti's, DL6AUI's birthday with champagne and rolls with hash and onions, as we did last year.
Well, that was exhausting!
Nevertheless we managed somehow the antenna setup of our 23cm mast and it remained upright (not as last year) : a first small happy end. We've learned our lesson! Meanwhile the rest of the team arrived from Greiz and we finished preparations until 1200ut 2 hours left to contest start and right before the rain started, not strong but constantly until  darkness.
According to our successful contact with DF0YY in May contest we decided to build up the microwave tripods on the same small hill containing a water cistern which guarantees a free takeoff from west over north to east. But is was cold and windy outside!
47GHz was completely renewed by Roland, DK4RC, containing now a brand new DB6NT amplifier and a mechanical waveguide switch. The output is estimated with about 50mW. It was quickly put on a separate tripod and we could hear the DB0FGB beacon through the rainy clouds at first go! Not a matter of course regarding the weather situation and the distance of >100km. That was promising!
On Sunday morning the sky started to clear off and so our expectations began to rise. Conditions on 23cm improved and we could log some I stations never worked before. Even on 13cm we had our first I in the log. Time for new records now! The temperature was quite low (about 4°C) and a strong wind was blowing from north. Some contacts on 24GHz were made quickly and with strong signals. But we failed with DF0YY even after some trials, we need a bit more of tropo propagation to make it, obviously. No problems at all with DM7A and OK1AIY/p, both 156km. As we asked Pavel for 47GHz he told us about very bad weather on his side and so we decided to postpone the 47GHz trial. Meanwhile, some of our old fellows kept us busy on 24GHZ for a while and after that we had some more time to optimize the feed on 47GHz. The DB0FGB beacon was always easy to find even with a beam width of only +/- 1.5deg. Around 1000ut we were ready again for the next try. A quick bearing check and QSY to 47088.200. There was a carrier strong and stable, was that OK1AIY/p ? One minute later there was no doubt about it because it was his voice calling us loud and clear. Not so easy to find a microphone and swith the right switches in that confusion but we managed it somehow to answer him quickly after his call. I think that Pavel was as surprised as we were concerning the quality of this QSO over 156km! The signals were strong and stable with speaker copy all the time. New CZ record was established and there is some more headroom left (look also here for details!) . Shift expectations!



The rest of the contest was business as usual. No crashes no failures, everything worked just fine. Here is a short overview :

Band QSOs ODX Call ODX Loc ODX km
1.2GHz 140 I0FHZ JN62AP 895
2.3GHz 54 I4CVC JN54WL 691
3.4GHz 27 G3XDY JO02OB 684
5.6GHz 26 SK7MW JO65MJ 549
10GHz 42 OK2TT JO80IA 426
24GHz 13 OK1AIY/P JO60LJ 155
47GHz 2 OK1AIY/P JO60LJ 155

So we experienced the second big happy end and we were quite satisfied with the contest though our competitors had some more QSO counts claimed. Lets see what the results are worth for!

We hope to see you again soon in the July contest !
