The ARRL 10m contest during the high solar cycle is always a pleasure and as 10m has done in the past it surprised me with some nice DX...7Q2T in  Malawi! My contacts were Europe and the U.S. with some South  America sprinkled in. The solar conditions were good with a K index from K1 to K3 but the Bz was in the negative numbers for most of the contest. This gave way to deep fading of signals to the point that if you did not get the contact information on the first try most often the signal was gone. This year I increased my contacts by 200 plus over last year and came close to doubling my score. I found each day the band opened to  Europe around 8 am local time and at around 11 am local it began to shift to the U.S. As the afternoon came South America would trickle in along with Hawaii Once again I was able to put PE4BAS fellow blogger Bas in the log.

The ARRL 10m contest happens this weekend (I got the date correct this time), and as we all know, 10m can be a band full of surprises. I once again put my ZachTek WSPR desktop transmitter to work for 24 hours. Below is a snapshot from Wednesday 19:00 UTC to Thursday 19:00 UTC. 

The graphs indicates that 10m becomes active around  1100 UTC, peaking at 14:00 UTC and staying decent until 21:00, when the band begins its fast closing for the day.

The RFI black book

 At the beginning of November, I posted regarding the journal I was going to start regarding my RFI. I wanted to log ideas to try, results from the ideas and detailed records of the RFI. In the past, it was scribbled on a paper here and there and when needed to refer to I could not find the notes. This was a great help and allowed me to track what did and did not work. 

I then blogged on December 1st regarding ferrites I had purchased. They were bought and arrived in mid-November and I had a chance to give them a go. Now in my post on the ferrites, I did mention I purchased a brand called Fair-Rite, which I felt where a very good brand. I wanted to make the first test for this product an easy access one. I have mentioned in the past our electronic Maytag washing machine always had issues with RF from my operating. When I transmitted the washers would stop and just hummed. If the machine was not being used but still plugged in and I transmitted all the LED  lights would come on and it would start to buzz. The only solution while operating was to turn off the power to the washer. In the past, I tried some snap-on chokes from MFJ and put them on the washers AC power cord, which did not work. I snapped on 2 of the Fair-rite chokes and to this day I  have had no issues at all with the washing machine. The machine can sit there powered on or doing a load of laundry and no issues at all.

Those of you who are regular blog readers know I have had my fair share of RFI that has affected my PC, washing machine, headphones and key. I have been doing some reading that all ferrites are not alike. Yes, they may be a mix 31 but there are good and very good ferrites on the market. I looked around at the popular dealers that dealt with chokes both beads, snap on and rings. I have read many good reviews on the Fair-Rite brand of ferrites. There were two electronic dealers I have dealt with in the past Mouser and Digikey. Mouser was where I ended up as I had ordered from them and was very happy.  I found the Fair-rite snap-on chokes I wanted and ordered them along with one Fair-rite round ring ferrite. These items shipped the same day and were at my door in no time. My mission with the new ferrites was to solve my PC  issue. When operating N1MM+ contesting program now and then (mostly at the most inconvenient of times) the Windows hourglass would pop up on my screen. For anywhere from 4 seconds to 20 seconds I was not able to transmit using any of N1MM+ macros. Not good when a station is waiting for a contest reply from me. The other thing that happened again in  N1MM+ the log window would just go black. The only way to solve this issue was to restart the program.
I have an idea what the issue may be and I want to see if this Fair-Rite product is truly a quality product or not. More on that in the next post.

The conditions for contesting were both great solar weather-wise and local weather-wise. The solar weather was very favourable during the entire contest which was nice. The sun has been very active these past few months and this weekend it was nice and calm. Local weather was just right for contesting as well...it was pouring rain and windy all weekend. Why is this great you ask..well during the contest slow periods no sun and the blue sky were calling my name to get outdoors. My goals for this contest were to have fun (check), run for 98% of the time (check), beat last year's score (double check) and hopefully have no radio or PC issues (check).

As always this was a very well-attended contest with lots of DX so even if you are not an avid contester there was an advantage to logging some rare DX. My radio was the Icom 7610 at 100 watts using the Hustler 4BTV vertical antenna. Max  CW speed was at 34wpm and toward the end I dropped it to 30wpm. For most of the contest, the Kp index was Kp3 and dropped to kp1 toward the contest end. The Bz index was in the plus for Friday and Saturday but headed in the negatives on Sunday. When the Bz dips in the negative numbers it accounts for problematic signal fading. At times the caller was there and then gone. 

I was very pleased all the way around,  the radio worked great, the PC and its software had no issues and the solar conditions behaved themselves. Mind you toward the end of the contest I  started to have a little brain fog and messing up similar CW letters such as H and S and on occasion transposing letters. This year I also made a point to not take things personally. What I mean by this is when asking for a few repeats because at my end I had either a close station wiping them out or another station calling me on top of the desired station. In the past when the station I was asking repeat from seemed to leave in a huff it used to bother me....well not anymore. In the past, I took things personally and that took the fun out of contesting....well no more. 

A very busy map of my contacts.

Some things that threw me off were stations coming back to me with "DE WXYZ". I would copy DE thinking it was the first two letters to only find out they were sending "DE" for "this is". I have my filter set for 400hz when calling CQ TEST and in crowded bands like in the CQ WW contest that is wide for me. I would have some stations come back to me way off my calling frequency. Most of the time I thought they were answering another CQ TEST close to me....but not so. I would end up adjusting the RIT make the contact and get back. But that was it and I am not by any means complaining just sounding off a bit. 

Well ok, just one more....those who when they send back their exchange would also send their call again which makes me think I messed up their call.  This became problematic when their call was "HSH" or "KH5" so made for unnecessary back and forth while others waited to contact me....or some would just step in with their call knowing the call was good the way I had it.  I also had fellow blogger Bas PE4BAS contact me during the contest as well.
When you hit 1750 CW contacts once you're done with the contest and in bed with your eyes closed you can still hear cw code in your head rolling around. I had a blast and am looking forward to the next contest.

Very happy with the outcome.

This coming weekend is the CQ Worldwide CW DX contest. You don't have to be a contester to jump in this contest. There will be some great DX  to be had so one can add contacts to an award you are working towards.  If you are a QRP op you can see how far your 5 watts will get you. At one time I even ran QRPp power and was amazed at the distances I made. The exchange in this contest is easy peasy a signal report (always 599) and your CQ zone. (Found here). If you are working your way up the contest code ladder this is a great time to log in some practice time. So double-click on your contest icon and roll in a few hours over the weekend in the contest.
