I awoke this morning to darkness and rain and according to the weather report, it's going to be all day. Over the past week, I have been having a rainy day of the mind. This happens now and then and it happens to everyone who is in the process of stretching the mind. I got up one day and for the life of me when I was doing my CW practising I was lost when it came to hearing the letters S and H. Which was which....I never had this issue for ever and now I am getting very frustrated as when I hear either of those letters I am at a loss which one it is!! At my speed of 34-36wpm if you have to stop and think you lose everything. With my practice simulator, I would replay a call sign over and over and it was only a guess when I committed to either H or S. This also made the CQ WW CW contest at times very frustrating and at times embarrassing for me. 

This has happened in the past and it's nothing new to those who are into Morse code. The word on the street is keep at it and the mind is an amazing thing and it will come around. I am happy to say that as of today for some reason I am back in the zone. I can't explain it but now when I either hear S or H I know exactly which letter it is. Below is one of my practice sessions and the proof is in the picture.

 Due to an active sun which brings us both good and bad conditions today was one of the bad days...or was it. Today I flipped the switch and listened to the bands and what did I find you ask? WI5D (once on 20m and once on40m) as a POTA in a park in Missouri, K3SLH as a POTA in Pennsylvania and LZ600PA as a special event station from Bulgaria. Yes due to the space weather, it was a slow day on the bands. On 15m and 20m one had to watch the waterfall as signals would just pop out and then soon after gone again. The way I look at it any day on the radio is a good day. It was not all glory on the bands I did have some POTA stations lost in the mud after my call out to them.

 I had the opportunity to get on the radio this afternoon and at the same time, I had called up the DX Heat cluster on my PC to see what was happening on the bands. I noticed a few POTA (Parks on the Air) stations being spotted and I know of a POTA site that gave more info regarding the activations. I was shocked that in all of 10 minutes, I made 3 contacts. From reading my blog roll Parks on the Air and Summits on the Air are very popular. All these contacts I made were CW but SSB is very popular as well. There were more that I heard but was unable to make contact with as they had a pileup and their signal slowly faded away. I give these ops lots of credit, they pick up and go, have a minimal setup and its very cold this time of year as well.

Hello and welcome to the 523rd installment of Linux in the Ham Shack. In this short topics episode, the hosts discuss the FCC removing symbol rate limitations, the ongoing WRC-23, Canonical MicroCloud, Ubuntu Budgie, Wayland and much more. Thanks for listening and have a great week.

My setup and the VE3WDM is my lic plate from Ontario

This past weekend I was busy with the CQ World Wide CW contest...go figure! The solar weather was not looking good and for most of Saturday, the Kp index was around 6 and for a short time moved to 7. I was shocked the conditions were still decent. On Sunday the Kp index fell to 2-3 which also gave better conditions. I entered as low power (100 watts), all band and unassisted meaning I did not use QSO finding assistance. The bands I operated were limited to my antenna the Hustler 4BTV which meant that was 40,20,15 and 10m. 

Spot in the middle of the Ocean is code garble SN70 I put zero and not the letter O

Some of my highlights were getting a call from fellow blogger Bas PE4BAS, KH7L and V51YJ. I think because of the conditions solar weather wise it limited me from Southeast Asia. I did spend a lot of time in the operating chair and toward the end of the contest I started to get what I call "code garble". I heard a call but it just did not register, I heard a call but entered numbers or letters on the keyboard that had nothing to do with the call and so on. For example, numerous time I had a call starting 9A call me and every time I entered 0A. I kept having to correct it and that meant time and good old 9A wondered what I was up too.  I ended up pulling the plug about an hour before the contest ended. 

My best hourly contact rates were in the 130's and at the low-end 50's. I have been practising handling pileups using N1MM logger. You can set it up to give you pileup simulations. Not that I am a big gun but when you get spotted on the cluster things can get a bit hairy at times.

The final results

During the contest 99% of the time I was calling "CQ contest" or running as it is called. My speed was 32-34 wpm. I find if your calling at 32 wpm you get replies at 25-36 wpm. When calling at 34wpm sometimes the comebacks can be very fast and mistakes happen. In this contest, the exchange is 599 (signal report) and CQ zone and that is filled in by the contest program. This means when your calling CQ contest you can go a bit faster as most slower callers most likely found your call on the cluster. When a serial number is involved a lot of contest stations slow down the serial number part of the exchange.

Overall it was a great contest and I look forward to it again next year. The next contest I am looking at is the RAC Canadian Winter contest in December.
