Comments

Had to run some errands before the contest so did not sit down to operate until 1215z (15 mins late). Stayed on the air almost continuously for the remainder of the 24 hours.  Two quick breaks and one for 12 minutes to eat.

Decided to do this contest old school.  SO2R, but no cluster.  I have gotten used to having lots of spots of multipliers, so it was good to remember the tension of having to decide when to stop running and look for mults.

You never know what you will get for conditions in the Summer. Was hearing Europe on 10 meters at the start, in the afternoon until after sunset, and again on Sunday morning. Worked some Europeans on 15 meters at 4 am local time here!

Even with tropical storm Elsa racing away, the low bands were quiet on this end.

 Must have been noisy down south and in Europe as I called a number of loud stations on 160m that could not hear me.  40m was so good I didn’t spend enough time on 80m so missed a number of “easy” HQ mults.

All antennas seemed to be working.  I think I have a problem with the stacking box on the 10m array.  Looks like it is time to do some work there.  The recently repaired 40m beam was hearing well but has an SWR problem that will need some investigation.

Did not hear a JA station on any band until Sunday morning when 20 finally opened that way. Had a few call in along with a BY and DU, which were welcome mults.

Ended the contest with a nice run on 15 meters CW.  I kept thinking I should go to SSB, but the activity never seemed to be there at other times during the weekend.  Where are all the phone ops?!

Thanks to everyone that was active and making QSOs.  Hope you had as much fun as I did!
