Comments:

This was very nice contest. 
Actually, we had 2 ½ ops. YU1YV is 50+ years old, and his contribution was
only 75%. Also, YT3M had a lot of work to keep us in good shape so he had less
time for contesting.
We had some minor problem with 160m antenna. Antenna itself was not so bad, but
at the same time, it was not so productive. Even, it was broken during the first
night, but YT3M fixed it during the second day and we enjoyed working over 100
W/VE on Sunday night.
Conditions were nice during contest and we have nothing to claim about that.
Only, something strange has happened with propagation on 80m, on second night,
and we culdn’t start any run. Well, we were there pressing F1 but apparently,
nothing happened on the other side of Atlantic. 
Why? Who knows... It must be some strange force that suddenly apears and solves
issues?
The 10m band was good, so we had to break our 20m run and work 15 stations on
that band.
Anyway, we are very happy with our achievement and we will try this again, with
some minor systematic improvements.

Antennas by YT3M :
160m low * Inv V 
80m low * Inv V
40m - 40shorty
20m - 3/3 short boomers
15m - 5/5 long boomers
10m - 6el Mega long boomer
1 x Beverage for USA 240m long

* During last few years we have noticed that usage of lower antenna produces
more gain in near filed. This is good to keep run freq clear and more fair than
using 3, 4, name-it KW which, somehow, become a standard WolrdWide. 
Also, usage of beverage antenna was our way to filter big local signals which
were presented on 160 an 80m.
