What a contest. What fantastic conditions. Especially over the pole. So many Russians!
We used to count the number of hours over 100 as a measure of contest success. This time I only had one hour under 100 in the first 24. Wow!
I turned on the scoreboard about 3 hours in feeling like I had a good start. Only to find N5DX and WA1Z already way ahead of me. A trend that would only continue. Even during 3 consecutive hours on Satruday morning with over 200 QSOs per hour N5DX just kept pulling away. WA1Z disappeared sometime on Saturday. That left me competing with N6MJ at ND7K. What? A W7 is keeping up with W1 in a DX contest?! Conditions must really be good.
I must have a hardware problem in my computer. It crashed around 17z the first morning. The MK2R+ software locks up hard and the only solution is to turn off the computer and restart. It happened again on Sunday at about the same time and I almost quit, but had too much invested in the contest at that point to give up.
160 was good the first night, but even better the second with no noise at all. I worked a number of 100W Europeans and even a few QRP.
The first night it seemed like 20 never closed. Loud Russians and then loud Europeans, with Japan mixed in the whole time. I missed a lot of 40m time because 20 was so good. The second night had the 20m opening, but not as good. And 40 was great at Eu sunrise so was able to get caught up.
The high bands were awesome on the first day. Just great the second. There was a period late morning on Sunday where I just couldn’t seem to get anything going. All while watching N5DX just keep pulling away.
Conditions to Asia the last 2 hours of the contest were great. I was even able to call CQ on 15 and get responses. A big help in my last-hour push to get to 6000 QSOs (far and away my personal best in a DX contest).
Mults were a challenge. It was hard to find time to S&P, and even when you did it was just stations sending a power and then dit dit. Callsigns seem to be optional in today’s DX cluster-powered contesting world. I have done assisted so much that I have forgotten the discipline of having to tune while running.
Lots of 6 band QSOs tell the story about how good all of the bands were.
Did not get out of the chair except for more than a few minutes in the first 26 hours. Then took a break to eat, then a short nap, then another short nap. Most I have operated as a single op in a number of years.
Unable to do 2BSIQ. Tried it for about 15 minutes on Sunday morning and just couldn’t Keep up. So this was almost all old school SO2R.
I did record the contest and there were some great rate and SO2R experiences. Unfortunately, the computer crash on Saturday did not continue the recording when I restarted. So missed a lot of the contest. Very sad since this one might be worth listening to during the next sunspot low.
Thanks to all the DX that spent their weekend working USA stations. Now to get ready for SSB in 2 weeks!
