Comments: 
What a great contest. Goal was to reach 1.400 QSOs, 120 Multiplier and a 6 points average to have a score over 1Mio points. Like in 2008 I used two 160m dipoles, two beverages (NA and JA) and additionally an L-antenna for 160m. The vertical part of the l-antenna was support by one of the towers so that the wire was just two meters away of the steal. This resulted in a very broad SWR on the 160m band and maybe even a strange radiation. But nevertheless I used the l-antenna the first night only and could make 866 QSOs with a lot of NA contacts.

The second night I hoped to get some JA stations and tried to find a free spot in the JA window (which is nearly impossible). I also noticed a slightly getting worse SWR on the l-antenna which I did not pay much attention. I only could hear JA7NI who gave out some points. No other JA. The rates were still ok so I continued to call CQ. But contrary to the first night, nearly no NA stations were heard. Between 2UTC and 4UTC I had rates fare below 16 Qs/h and a lot of frequency fights. Seems to be a new sport. If you lose the QRG to a weak DX station that is still ok, but if someone calls right in the middle of your CW filter with S9+20db CQ, that is something different. So we both made no QSOs for 10min, than the station left the QRG, I could make a couple of QSOs, and than the next one tries to steal the QRg. So I looked for a new place to stay and after 15min… (grrr)

I found some nice pileups where I never heard the DX station. V31YN was heard only once within a 10min period when I stayed on his QRG. The remaining time whole EU was calling without even to have a slight chance to hear the DX. I never found 6W/DL2RMC, but I think I found his pileup. Luckily he called in a couple of hours before contest end.  A nice surprise as KL7HBK who called in and was very difficult to copy. There is no beverage pointing to north so had to copy his signal on the TX antennas with all the QRM.

In the very early Sunday morning hours the SWR was real worse on the l-antenna and the rates were so unproductive that I decided at 05:30 UTC to make a last attempt or go to bed early. I choose a place on the upper 160m band and used the stackmatch to reduce the SWR (or to move the high SWR away from the PA to be able to have more output..) and was rewarded with a two hour NA run like in the first night. On Sunday morning I had 1525 QSOs in my log.

On Sunday evening the SWR was so bad on all three antennas that I was not able to transmit above 1830 anymore. What had happened was very simple: I had temperatures just below 0 degrees, a slight wind and fog. This mixture created an ice shell on all wires (0,5cm). The dipole designed to the upper 160m band luckily still had a SWR around 2 on 1825 so I used this one for the remaining hours. Like on Saturday evening I could find no JA stations on 160m. Luckily JH3PRR called in for my JA multiplier.

At the end I made 1681 QSOs, plus 40 dupes, and 119 multi’s. 
17% (295 QSOs) DL, 15% (260 QSOs) W, 7% (122 QSOs) UA
