My favourite contest. And this year the windy weather kept away at the right times.
I didn’t do the full 24 hours but I didn’t want to be constrained to 12. Previous experience suggests that it’s pretty slow between midnight and 4am, and I’m still not 100% after flu some three weeks ago so I ended up not appearing again until 5am. Looks like I missed a 20m long path VK/ZL opening. I also had to run an errand in the afternoon. Nonetheless, I’m not happy at how my Q totals compare to 12 hour entrants with theoretically less capable stations. I’ve had a look at RBN comparisons and I’d say there wasn’t much in it RF-wise, despite beam vs. wires.
I used N1MM for the first time in anger since becoming all principled circa 15 years ago and only using Linux. Previously I used WinTest and wine but now I have a dual-boot machine which came with Windows 11 I’ve switched to using that with N1MM, just for contests. N1MM supports SO2V whereas WinTest does not. As it turned out, I abandoned SO2V in this contest because of the long gaps needed to effectively S&P. I can see how SO2R would be far more effective because you must spend long periods CQing and therefore are able to tune around more continuously. You keep a presence on the band also, which I think is important because there are a lot of stations out there who only S&P.
N1MM takes a bit of getting used to after WinTest. I was the source of a few dupes early on because I didn’t understand what the check call window was telling me. Apologies to those stations! Also, unless I’m missing something, I wish there was an HQ stations worked by band display. It was only after the contest I realised I’d missed GI5WS on 80m.
My noise floor is raised on 80m due to VDSL, and people were working stuff I simply couldn’t hear. No VKs or ZLs were worked on that band, but I didn’t seem to have a problem working what I could hear, despite backing-off the power to keep the gamma capacitor from arcing on the shunt feed. I also know I have SMPS-like noise on 10m when beaming SSW, but it didn’t hamper things much once the band had opened.
On the plus side, the new PC monitor has solved the display turning off with RFI problem. I bought it after AFS CW but found it was doing something similar in AFS SSB, but it’s a different problem. It seems there’s an issue with HDMI pick-up of the 1K-FA’s transformer magnetic field (and the rotator control transformer when you turn it on or off). Using USB-C instead seems to have solved that problem.
One of the down-sides of a beam is knowing where to point it! ZS1C was off the side of the beam when he called me at 21:30 on 20m and I nearly didn’t complete until I copied the prefix properly. It was also a dilemma as to beam long path or short path to VK/ZL on the Sunday morning. I found that 20m on the Sunday morning was still better on long path whereas 10m was better on short path, but it takes a long time to turn the beam. I never found ZD7BG, and I thought I spent enough time tuning around – probably too much. Some lessons learnt on the pointing front. Oh for a stack!
Some highlights: being called by AP2TN and VU2JOS on 10m; working V85NPV on 10m (who wasn’t actually in the contest). In general, it was really great to work so many VK/ZL on 10m.
I really should have moved V4/G0TLE from 15m when he called but I just wasn’t on the ball.
I think the report card would have to read, “room for improvement”.

Thanks to all the travellers, and despite my down-beat report I really enjoyed it!
