#CQWW WPX SSB Contest 2023 review

   This is one of the biggest world wide contests for HF amateurradio. The aim is to work as many different stations preferable DX. Multipliers are the different prefixes (WPX=World PrefiX) and DX (stations from a different continent as yours) count for a different amount extra points. Since I had limited operating time this weekend I had no goal, however this changed sunday evening. Propagation didn't look good because of a coronal mass ejection from the sun which wiped out most of the radiosignals on 14MHz and above at friday. It seems the propagation was still not recovered at Saturday. I had to work that day so I was unable to participate at that time, I don't know if I missed something though. 

  I started late Saturday evening and things didn't look allright as far as I could experience. I could barely hear some stations on 10m so I started on 15m. The band was full of DX and the experimental squalo antenna did a good job. I worked my share of DX for shure not knowing what propagation would be next day. I even managed working 2 contacts on 10m with EA8 stations. Quite early I went down to 40m which was also open into Europe and a few DX stations after midnight. At 00:30 I decided to run on 80m. Normally to get a good run it takes about 10 minutes of calling till you get some spots on the cluster. This time it took me only 3 calls to get a good run for about 1 hour, I worked about 100 stations. After a few contacts with DX on 40m I decided to take some sleep to be fresh Sundaymorning. This also because it is always the weekend the clock changes to summertime. 

Setup WPX. Icom-7300 100W, Doublet 2x20m
inverted-V, 10m LFA 4 elem.,
experimental square halo

I checked my last years efforts in this contest and noticed that I heard a lot of DX but couldn't work some of it. This year on Sunday it was different, I could work DX without much problems or calling. Actually I worked some DX I could barely hear, but they could still hear me. Worked CY0S from Sable Isl. on 10m late in the evening. I heard him in a huge pile-up and thought I would never have a chance. But I thought I just try it once....surprisingly I was heard at the first call, it was an easy contact. On 10m with the big 4 element LFA I had this most of the time actually, with the right conditions it probabely is radiating a huge signal. 10m opened early with excellent DX on the band to most of Asia, I never ever worked so much stations from China, Japan, Thailand and some countries in between. Last year I had no luck working 9N7AA from Nepal, it was easy to work him this time. The experimental squalo antenna also did a great job on 20m and 15m. The fun is that it is omni directional so if there are skewed paths, long path or short path propagations I wouldn't know. This way I worked unexpected DX, like PJ2T and J68HZ early in the morning on 20m, normally these are only heard in the evening. Propagation on Sunday was crazy anyway. I had the idea the whole world was upside down. What about Australia on 10m with 5/9 signals late in the evening, normally only heard in the morning. I also worked a Japanese station very late in the evening on 20m, again with excellent signals. It was all really crazy. Anyway, not really that important but to get a good score I think you need to divide your time/contacts equally over the bands if they are open. So, I think I divided it well this time. It was also my goal to go Sunday when I reached 111 contacts on 10m. I decided to try and work 111 contacts on all different bands except 160m. But for fun my last contact of the contest was with YT8A on 160m while tuning my 10m beam on that band. Actually compared to last year I worked almost the same amount of stations but in less time.

List of DXCC worked during the WPX 2023

Some interesting things I like to mention for the personal archives this contest:

- An increase of Chinese operators. Their modulation is always overmodulated and their english is difficult to understand. But at least they are there!

- Russian stations are back!

- Some stations from continents I didn't expect did show up on unexpected times, Like Australia late in the afternoon on 10m and west-indies early in the morning on 20m.

- Worked my QSL printer from the Ukraine UX5UO Gennady on 15m. Worked OY1R Regin from Faroer Isl, on 80m. 

- For the first time since long in a contest I worked a new DXCC (ATNO) FK8GM from New Caledonia. I applied for a QSL and Eric was so kind to send me one!

New digimode CW8

  A publication in the VERON monthly magazine Electron last month is about the new digimode CW8. So far not much is known about this mode since beta testers have to keep this a secret. Test are currently made on the 60m band. It is not known how successful they are. It seems that this digimode is a mix between CW and automation like the multi streams in MSHV. CW8 is mainly being developed for contesting. Decoding is probabely done with a kind of new AI decoder. I've written about this in this blog a few years ago. However 2014 was just to early for the development of software like this. 

Part of the Electron publication

  Some details: 8 streams of CW in 400Hz bandwidth. 7,5 second timeslots. In computer assisted mode (automatic) it is possible to make 2x8=16 QSOs per minute (QSO rate could be 960 QSO/h). Software will be available for Windows and Linux and macOS. Software is already tested with N1MM+ and Write-Log in Windows. Development for Android has been started.

As readers of the Electron magazine we had the opportunity to apply as beta tester. Unfortunately only 120 testers were allowed. Personally I just forgot to apply due to other obligations (job). But so far I heard signals on 60m.

Unfortunately UCIC refuses to give more info on this and wants to be shure the software works well before they will release in to the world amateurradio community. Expect they will have more information at the end of this week.

#60m CY0S Sable Isl. worked

 

I saw CY0S spotted on the DX cluster and since I have a day off the job I was able to be on the radio. I didn't have much hope since the new solar panels from our neighbours give me a lot of high QRM (S9+10dB) on 60m as you can probabely see on the waterfall. However the signal lifted a bit and I was able to receive their streams for a new one on 60m.
