This was an SO2R operation. The audio is the same as heard by the operator. When headphones are ‘split’, the left channel is from the left side radio and the right channel is from the right side radio.
Two files were corrupted during the recording process. No audio is available during Day 1 0000-0022z and 1320-1357z.

Comments:
Wow, who would have expected a score like this with the conditions predicted for the weekend?!
Had planned a casual effort, but the activity and conditions were addicting! Once I started, I just couldn’t stop operating. Luckily my family is familiar with this addiction and knew to just ignore me until the contest was over.
Highlights:
Low bands were great. Knew it was going to be good when I called Europeans on 160m and they could hear me on the first call. No QRN here in the USA or Europe really helps the scores.
Conditions on Saturday morning. I woke up around 1130z and did some low band DXing. As I was finishing on 40m I moved the second radio from 80m to 15m. Whoa! The band was filled with booming signals. My first CQ at 1156z resulted in 201 QSOs in the next 60 minutes. I completely skipped 20m for the morning.
40m on both afternoons. No matter how many times I do WWCW from here I can’t get used to going to 40m when the sun is still up. Got there at 21z on Saturday and had 4 fantastic (100+) hours in a row on the same frequency. A little earlier on Sunday and almost the same result. Thus the big 40m QSO total.
80m Saturday night. I slept for two hours between 02-04z. Worked some DX on 160m and then found 3506 available. Had 3 hours straight of great rate (until ED9M decided it was his frequency). I don’t have the loudest signal on 80m so it was really nice to get so many QSOs. Definitely helped the score.
10 meters. Worked one European. Worked ST2AR for the only zone 34 heard all weekend!
Elecraft K3. This radio has the best receiver. It would have been impossible to hear so many of the weak stations, especially on 40 and 80, without it.
Russians and Eastern Europe. Fantastic activity from this area on all bands. I love the new Russian callsigns. Some of them reminded me of prefixes from long ago. UD, UC, RJ, etc.
USA record? The old USA record was from the year 2000 (8.7M with 4484/161/531) and included 1189 QSOs on 10m! The difference this year was the balance across all bands. A rare occurence.
Lowlights:
SO2R. Had 208 second radio QSOs. Rate was so high I had almost no time to work on the second radio. 🙁
Not operating full time. Since I had not planned a serious effort, I did not do any special preparation for food or sleep. Also spent much time the first night DXing. It was only at the halfway point that I realized the score was special and I should be more serious. The second day was full attention and motivation!
People who don’t send their call enough. I think I complain about this every year.
The increase in DX Cluster (and skimmer) use keeps making it worse. Part of the challenge of single op.
