Comments:

This year ARRL was one of most strange condx I have ever remembered.

I started on 40m, but it was disaster, band closed, somebody forget switch this
band on. 80m a bit better and 160m with one fine opening, furtunately I was
there. Morning with cca 40 % of expected rate. Saturday with better rates on
high bands, but 10m dead. Early and suddenly closing of high bands. Next night
started with 40m in good mood, 2 hours of rates nearly 90 Q/h, but at 0300Z
again switched off. Few attempts to try it at 80m, but also suffering. Top band
with no chance to new calls. Sunday opening of high bands was early, but rates
around 40 Q/h. Then one of the highlight of the contest - 1 hour of 10m
opening. I was able to hold "QSO meter" over 200 Q/h for few minutes
and catch worthy mults. Withal 2 hours of great opening of 20m.

Not a lot of intruders, but with more aggressive tactic. Funny unnamed SP M/S
station. Sat suddenly just on me and pretend "I hear only NA", deaf
to my few QRL/QSY PSE. OK, I tried to test his antenna diagram by quick sending
of USA call just 1 time. His "5NNKW" was immediate. Then only one
request to QSY was enough.

I built TX3A RX antenna to NA direction and it was good choice. Not evidently
better at 40m, too low signal level at 160m, but killing big portion of 80m
noise.

Thanks to all participants, for patience during QSBs.
