CW contesting cut short.
This weekend was the WAG (Worked All Germany) contest which I entered CW low power and unassisted. About 10 minutes into the contest things started to unravel, I was on 10m calling CQ TEST when my contest software (N1MM+) had the contact log window turn black. It came back to normal within an instant but that is never a good sign. Next, I pressed my F1 key to send CQ TEST again and it did not respond, I pressed it again and nothing. Then all of a sudden the rig keyed and the macro started to send...twice. Then the issues got worse as when I had a station come back to me and I responded with my exchange the macro would not send right away. It was very confusing to the answering station and as he sent his call again, it was then my exchange macro decided to send.
It was time to shut down and get things sorted out. I have had this issue in the past and thought I figured it out. In the past, my wired Lanovo mechanical keyboard was picking up RFI and causing me problems. I was looking for a fast fix and added some mix 31 toroids to where the cable enters the keyboard. I now have toroids at either end of the keyboard cable.
I then fired up the contest software and called CQ TEST again on 10m. For over an hour, I had no issues and hoped I had fixed the issue. This was the first time this issue had ever shown up on 10m in the past it has always been just 20m but of course now that I am contesting "MR RFI" changes things up. Heading up to 20m and again while calling CQ TEST I had the N1MM+ contest log window go black again. It was time once again to shut things down as I couldn't contest in this situation.
As I sat there and went over things I knew in the past I had had issues with my wired mouse, I went wireless and the problem was solved. Maybe it was time to go with a wireless keyboard? I have a Logitech K830 hanging around and thought I would put that into service and see what happens. Of course, the keyboard's rechargeable battery was dead and needed about an hour of charge time before I could use it. That gave me time to label the keyboard and look up the instructions on how to pair it. Logi wireless keyboard.
I was up and running again with the wireless keyboard and things were working just fine! This is a much smaller keyboard and I found myself hitting macro F keys when I was supposed to be hitting numbers. This also is not a mechanical key-type keyboard. I tend to be heavy-handed while my hands are resting on the keyboard waiting for the CQ TEST macro to finish. The keyboard was so sensitive by mistake that I would type letters into N1MM+ call box. When this happened my CQ macro stopped (as it should) I had to lighten up my heavy hands while I was using this keyboard.
While waiting for the keyboard to charge I made my way to Amazon and ordered a full-size mechanical keyboard. I was sure this was the solution to the issue and so far I was right. It was getting more toward evening and 40m looked like it was hopping. When I pressed my F1 CQ key my N1MM+ , Win4icom radio control software and the web page I had open all disappeared! With everything restarted I tried again with the same results, it was time to pull the plug and think about things over the evening. The wireless keyboard was not the answer. It was time to get back onto Amazon and cancel the keyboard order.Winkeyer with ground lead to main ground bus
As the wheels in my head started to turn when using the wired keyboard the only program that was ever affected was N1MM+ and not Win4icom radio control software or the webpages I had open, it was always just N1MM+. When I started to use Win4icom radio control software along with N1MM+ I needed to purchase a Winkeyer USB unit for the CW macros in N1MM+ to work properly. The Winkeyer is directly involved with the sending of code and it's part of the chain I have not paid any attention to. All outgoing cables had 31mix toroids on them BUT I realized the unit was not connected to the station ground. On Sunday morning I opened the Winkeyer and connected a station ground wire to one of the PC board mounting screws.
I began contesting and all was good on all bands, my fingers are crossed BUT I have had this false hope in the past. Today (Monday) I have my weekly Medium Speed Contest (MST) in the morning and afternoon. It will be a good test to see if the issue has been fixed.
Also, I posted my issue on the Groups.io N1MM+ site and had some excellent feedback. One common thread was the USB outer metal shell on the PC. I was told most of the time they are floating and not grounded and this can cause issues. I have a lot of USB cables connected to my PC for radio-related things. I was given a very good idea on how to ground them but more on that in another post.
UPDATE: This morning and this afternoon I took part in the MST contest and called CQ on all bands without any issues. Maybe I have the RFI issue solved. BUT in the past I have done the happy dance to only be greeted with RFI....so we are keeping this celebration very low key.
