CQ WW CW 2020 contest is on the books!


 This past weekend was the CQ WW CW contest which if I can I always partake in.  This year I made it a point to set aside the time to indulge.....well I'm retired now so it's really not all that hard to set the time aside. But this time around it was going to be a toss-up whether the monitor troubles I was having were going to give me issues.  In a nutshell, if the monitor was turned off it was a 50/50 chance I could be greeted with a black screen. If that was the case I then had to play around starting and restarting the PC and turning the monitor off and on to get it working again. My solution was during the day when I took a break from contesting was to leave the PC and monitor on. This seemed to work very well and it was only when the PC was turned off at night did I only have one time with issues trying to get the monitor up and working. 

 I was really looking forward to seeing how the new upswing in the solar conditions treated me with my 100 watts of power into a mediocre Endfed antenna. I did have plans to hit the airwaves on Friday evening but Julie and I decided to have a date night COVID style at home with a home-cooked meal and a movie. On Saturday and Sunday, I was able to spend a good amount of time in the operating chair. The new solar conditions made the contest a pleasure!

 There was really no dead bands from 10m to 80m in my case. The highlight for me was making contact on 2 occasions with Hawaii both times on 15m. There were other possible opportunities with some exotic places but the pile-up was that of a DXpedition. I did not want to waste valuable time to make or not make the contact. 

It was a pleasure to see 10m meters open and it had me rope some contacts in South America and Europe and well as the U.S. I also gave 80m a shot as I can use my external tuner  (AT200Pro II) to get a decent SWR. This opportunity netted me some U.S contact points. 

My score for sure is not going to be in the CQ WW CW record books but I really enjoyed this contest and the propagation brought even more joy and really had me staying in the radio chair to make contacts. 

Below is the score breakdown: 

Contesting at QRPp levels!


Yesterday I dabbled in the OK/OM DX CW contest for about an hour and a half. This time for some fun and interest I entered QRP level but lowered my power to just one watt. Propagation has been surprisingly nice over the past week or so and I wanted to give the new solar flux a test run. My radio is the Icom 7610 and my antenna is a slopped Endfed antenna at about 25 feet. I stayed on 20m as the radio gods seemed to be smiling on me there. I made only 10 contacts as I was not in the contest for scoring just to see how the fishing was with one watt. I was only asked for repeats regarding my exchange twice other than that the 1 watt made it through. 

Because I was operating at only 1 watt I also wanted to take the loss of my SWR into account. I checked with my antenna analyzer and the CW portion on 20m my SWR was 2.3:1. According to the power loss at various SWR readings chart at 2.3:1, I was in around 15% so this took my 1 watt down to 850 milliwatts. 

Below are the results of my QRPp contest efforts:

Perfect Straight-Key Morse Code? Can It Be Made Without Machines?

What is the proper (and most efficient) technique for creating Morse code by hand, using a manual Morse code key?
Ham radio operators find Morse code (and the CW mode, or Continuous Wave keying mode) very useful, even though Morse code is no longer required as part of the licensing process.
Morse code is highly effective in weak-signal radio work.  And, Preppers love Morse code because it is the most efficient way to communicate when there is a major disaster that could wipe out the communications infrastructure.
While this military film is antique, the vintage information is timeless, as the material is applicable to Morse code, even today.  This film has the answer to the question, “Can a person craft perfect Morse code by straight key, without the help of a computer or machine?

The International Morse Code (sometimes referred to as CW in amateur radio jargon because a continuous wave is turned on and off with the long and short elements of the Morse code characters) is a type of character encoding that transmits telegraphic information using rhythm. Morse code uses a standardized sequence of short and long elements to represent the letters, numerals, punctuation and special characters of a given message. The short and long elements can be formed by sounds, marks, or pulses, in on off keying and are commonly known as dots and dashes or, dits and dahs. The speed of Morse code is measured in words per minute (WPM) or characters per minute, while fixed-length data forms of telecommunication transmission are usually measured in baud or bps.
Why is it called Morse code? This character encoding was devised by Samuel F. B. Morse, the creator of the electric telegraph. This Morse code came in two flavors, in the beginning years of its usage. One was in use by the railroads of America, and is known as American Morse Code. And, there is a unified, internationally-used version (adopted by radio operators), now known as the International Morse Code. Now, when most people refer to Morse code, or CW, they mean, International Morse Code.
Currently, the most popular use of Morse code is by amateur radio operators, although it is no longer a requirement for amateur licensing in many countries. In the professional field, pilots and air traffic controllers are usually familiar with Morse code and require a basic understanding. Navigational aids in the field of aviation, such as VORs and NDBs, constantly transmit their identity in Morse code.
Morse code is designed to be read by humans without a decoding device, making it useful for sending automated digital data in voice channels. For emergency signaling, Morse code can be sent by way of improvised sources that can be easily keyed on and off, making Morse code one of the most versatile methods of telecommunication in existence.

Skunked in the 2020 NJQRP Skeeter Hunt!

The setup 
Last weekend on Sunday was the NJQRP club QRP Skeeter hunt I received my Skeeter number close to the Sunday start date as I was not sure if I was able to participate but things turned in my favour Sunday was open for the contest. The morning here did not look too promising as there was a steady rain, but the weather reports were calling for a nice sunny afternoon. This was important as I was planning to set up in the backyard in our dining tent. 
Just in case it rained

The weather report was correct and the skies cleared and things looked just great for operating outdoor. For my set up I was going to use my Elecraft KX3 that I put together from a kit, battery power, Palm mini paddle and finally the antenna was a mag loop. I was on checking out 20m to see how it was sounding before the contest. It was not all that great but I was coping some station so the only thing to do now was to wait for the contest to start. 

My QRP signal was being heard.

To make a long story short I was on for over 21/2 hours and I did hear some skeeter station but only at the noise floor and they were soon gone. I had my Mac laptop with me and I was checking and found some spots but I was just not able to hear ANYTHING! I did check the Reverse Beacon Network to see if my QRP CQ was being heard and it was all the way in Finland as OH6GB heard my signal. 

My score for the contest was a big fat ZERO but I did get out, had my KX3 running and had a nice time outside. 

The annual 13 Colonies special event.

The annual 13 Colonies special event  (please view link to learn more about the event) was going on during the RAC Canada Day contest on July 1st. Last year I read about this event on Larry W2LJ's blog last year and he had a posted about it as well as this year. While I was operating the RAC Contest I found over and over a number of the special call letters from the 13 colonies event kept popping up. I then decided my operating would become contesting /13 Colonies Event operation. I was shocked that by the end of the evening I had a total of 9 of the 13 special calls in the log. Now there really are 15 stations you can contact as there are 2 bonus stations and I was able to snag one of those as well. I was on last evening but was unable to secure any additional contacts. The fun begins now as I have to search out specific calls that I need. Larry W2LJ did mention that the event can get very busy and last evening I was listening to a station (that was already in my log) and it was so busy and the pileup was crazy he had to operate split!
I will be on again this weekend to see if I can get all 13 stations and the bonus stations. Stay safe everyone and thanks very much for taking the time to stop by the blog.

CQ WPX CW contest summary.

Another CQWPX CW contest has come and gone and this year for me it was a parttime effort as the weather was great here and many outdoor "Stuffs" had to be done. I was shocked to see 10m open and I was able to bag 7 contacts there. During my first leg of the contest on Saturday, I found it very hard to contact any Europian stations. I did make one into Ireland and that was it. The second leg of the contest was Sunday and it seemed that Europe had opened up just fine and I was making DX contacts. The only issue during the short time I was taking part in the contest was the XIT issue which I posted about a few days ago. The other issue was right at the get-go of the contest, I was not able to get the N1MM CW macros to key up the Icom 7610. I have been working QSO parties Win4Icom rig control software looks after N1MM+ as 3rd party software. I do this because I can control the 7610 via my mouse using Win4Icom software. So things like band changes, fine filter adjustments, APF on and off and so on. I did not want to play with the issue for too long as I was not really going to be in the contest for all that long. I ended up going back to old school operating.....well almost old school no paper and pencil yet. I shut down Win4Icom and configured the N1MM+ com port to talk directly to the 7610. In minutes I was up and running again.
without issue and not an issue! Most of the time I get on the radio the day before a contest and test out the rig, software and keyer to make sure all is well.....guess what I failed to do the day before this time? My setup is as follows, I use
Below is the contest breakdown:
20m          73 contacts
15m          20 contacts
10m            7 contacts
Total      100
Score 18,778
WPX        83

One Aspect of Amateur Radio: Good Will Ambassadors to the World

This article is part two of the series taking a look at band plans and gentlemen agreements.
See part one, here: Land (er, FREQUENCY) Grab.  See part three, here: In Response — Can’t We All Just Get Along?

Displaced and Marginalized

There are some unhappy amateur radio operators in the world of shortwave operations. Users of Morse code, and digital modes other than the highly-popular modes engineered by Joe Taylor, K1JT, feel displaced on the many amateur radio bands where Joe’s wildly-popular mode FT8 has erupted.

Joe (born March 29, 1941), is a friend of hams everywhere, and is an American astrophysicist and Nobel Prize in Physics laureate (https://g.nw7us.us/2Ptquv1) for his discovery with Russell Alan Hulse of a “new type of pulsar, a discovery that has opened up new possibilities for the study of gravitation.”

Many have asked questions like, “Did Joe Taylor K1JT Destroy Amateur Radio? Did Joe Taylor K1JT, Nobel Laureate and noted friend of hams everywhere, accidentally destroy amateur radio?” This question remains relevant, even as more and more FT8 operators take to the HF bands to chase wallpaper and awards.

FT8 Has Validity and Usefulness

Full disclosure: I administer a Facebook group for FT8 and FT8-related modes, because I believe that the mode has a valid place in our amateur radio technology portfolio.  Here is the Facebook group URL, if you would like to join the fun: https://www.facebook.com/groups/FT8.FT4.HF.6m/. Understand, I have used and will continue to use FT8.

Because it has a place, it stands to reason that everyone should become more aware of the impact of using FT8 on the bands. It also stands to reason that it should be used ethically, and in the best spirit of amateur radio.

Many amateur operators use the FT8 digital mode as a novelty when there isn’t much else happening on amateur radio shortwave bands. One of the great things about it is that you can tell when a band is open–even though you don’t hear any other signals of other modes on the band in question, you very well may hear the roar of FT8 on the band where propagation actually exists to somewhere else than your QTH.

Others use it to finally get their DXCC, or WAS, or other award and wallpaper. This is especially popular during this season of the sunspot cycle where there are no sunspots–propagation is limited to lower-HF amateur bands because there’s just not enough solar activity to energize the ionosphere enough to open up the higher segment of shortwave.

FT8 Has Limitations

Can FT8 be used for two-way conversations? No. However, the JS8CALL digital mode is designed from the FT8 mode, by changing the protocol in a way that allows free text. It is designed for ragchewing and the new version 2.0 offers three modes of chat with 50 Hz and 16 wpm, 80 Hz and 24 wpm, and the turbo mode at 160hz and 40wpm with turbo only having a 6-second turn around time. The designated frequency is 7.078, which many find much nicer to use.

However, many find JS8CALL combersome, and non-intuitive.  How fast and how reliably can it handle critical messages, say, during an emergency?  I’m sure the software will improve, but how good is the protocol?

A mode such as Olivia has been field proven, and time tested.  It can reliably handle traffic.

The Rant

During the early days of widespread FT8 operation that came with the first public non-Beta release of FT8-equipped WSJT-X software, I tried to reason with the FT8 development leadership team. I made a polite attempt at explaining how incredibly rude they were in purposefully programming into the software the default operating frequencies such as 7.075, 14.075, and so on.

One of the main leaders of that team slammed me and stated that “we only suggested those frequencies; the operator is free to change them.” Additionally, he stated that the team used a common QSO/Mode spotting website to see what digital modes or other operations (like CW) were sparser. They perceived that the frequencies they proposed where no longer active because they saw few if any spots. They thought that no one would care.

I explained that a single website-spotting strategy was illogical and very lazy. This is true for several reasons, at least.

I guess you have to have a Ph.D. to know better than any average ham who went by gentleman’s agreements. I have an extremely dim view of JT and his disciples. CW is not the only operating group he’s engineered out of traditional slices of spectrum. Olivia, and other modes, now have been pushed down into PSK subbands, and everyone is feeling the crowding. As far as my thinking of FT8, well, it is radio, but it doesn’t foster goodwill and building serious communications skill. IMHO.

Play Nice, Be Positive and Polite. Smile.

I’ve received wise counsel from a number of fellow amateur radio operators.  They implore us to not promote hostility between “us and them.”  That even though the WSJT team is playing the playground bully, we should not be vengeful, but polite and willing to negotiate in good faith.

If we don’t play nice with the bully then the bully won’t play with us.  And, the general public will side with the bully because the bully has the nice toys…

Good negotiations, though, take a willingness by both sides, so that conversation evolves,  resulting in positive, cooperative actions embraced by both parties. There are other amateur radio operators who have made attempts to open up talks with Joe and crew.  What are the results, so far?

We can hope that Joe Taylor and his group of developers and leadership take a proactive role and join a conversation that is with a wider group of amateurs than just the WSJT enthusiasts.  We hope that they will play fairly, and cooperatively, with the rest of the amateur radio community.
