QSO rate

Our comments

Many thanks to all of you who made QSO's with PJ4U.

All of the contest time except first 6 hours we experienced strong noise coming from North direction ranging from 5 to 9 on S meter. Noise level was different depending on band and time. There were short periods of time when noise disappeared (shortly after the rain). All our attempts to avoid the noise, including use of noise blanker (ANC-4) and spraying water on nearest 6 kV power line pole (advice of QTH's owner), did not give any result. Sometimes it was possible to reduce affect of this noise by turning antenna to East or West, but there were moments when it didn't help much. We often turned our antennas not to the best path direction but to the direction where noise was with lowest level (mostly East).
We must say sorry to all of you who were not able to make QSO's with us or spent much time to make QSO. We are sure this noise affected our result pretty much.
80 m band were unusable most of the time due to noise mentioned  before. We had no antenna for 160 m, but seems that it wouldn't be very useful because of the same noise.
