All of us are at one place or another in our CW journey and with each path there are up and down times. Times when things connect and other times when there is a disconnect. If you think about it this is not just CW that operates this way. When you are learning to drive one day you can parallel park like a pro and the next day you could not do it if your life depended on it. Learning the times table back in school and you are great with the 9 times table....then in class, you are asked 9x7  and you go blank. Well, going beyond ICR can be the same way. Is there something beyond ICR you ask.....by golly Miss Mollie there is! 

Learning is an adventure no matter what you are challenging yourself with. I am a firm believer that to keep the mind, body and spirit healthy you need to be challenging yourself. This brings me to the next step beyond ICR.  It is the art of words and Q codes training and it is different from  ICR. In my humble opinion, I do feel you should master ICR before you jump into word and Q code recognition.
If you have ICR pretty much happening for you the next step is instant recognition but with a twist. Your brain is very powerful and I can't emphasize this enough. Now understand when I say powerful it does not necessarily mean this next step is going to be a breeze. Remember you have trained your brain to hear a letter or a number and recognize the sound and in a split second.
Now your brain is going to hear QTH, OP, WX, RIG and so on it has been conditioned to tell you Q  T  H. Well it is time to change it up again but not to worry your brain can compartmentalize things with practice. 

How does this new adventure work you ask? Let's go in reverse for a moment and go back to when you were learning ICR. You knew dit dit dit dah sound was "V" as you hear each dit and dah but for  ICR to work that was just too slow and you would get lost and get behind. Oh, which reminds me of the art of copying behind....but that is another post.... moving from copying each dit and dah to ICR you had to speed up the sending of each letter so it was impossible for you to hear each dit and dah but a sound. Learning the sound of each letter was the key.  The brain can handle that with no problem as you know if you have a grip on  ICR. 

Words and Q codes instant recognition is the same, you have to speed things up a little but just a little. Your brain has to hear what QTH sounds like and not Q  T  H. Impossible you say...I bet we all know CQ and 73 at any speed and don't hear the ICR equivalent of each letter. Your brain will put the new word and Q codes in a new compartment in your brain. Soon you will train your brain for words and Q codes. Keep reviewing your ICR as well and in time both will blend into one compartment in your brain.  The key to word and Q code instant recognition is speed up the sending just a bit. You want to hear the sound and each letter as ICR.

As for programs for learning words and Q codes, there are many programs out there that will send you anything a different speeds. If you have mastered ICR you will be aware of some programs that worked for you and chances are they also will function as word and Q code trainers as well. Just like with ICR work with some words or Q codes and then move on to more once those are familiar and then add more. Another excellent way to learn is to also turn the power on your rig to zero and practice sending the words and Q codes you are learning. The more involved your body is in learning the easier moving ahead will be.

Results from the RAC 2021 Survey

In this brief article, I focus on how much transmit power is typically used on the HF and microwave bands. Survey respondents were asked about what they consider “typical” usage although these settings can certainly be different at any given operation. The results do give the reader a picture of how amplifiers are used on these two broad segments of band allocations by Canadian ham operators.

In Figure 1 (click for larger image), the maximum power used to transmit on 160-6 meters is displayed in a pie chart. Although many may not agree that 10 watts is QRP power, we are using that convention here. About three-fourths of the survey respondents say they use between 10 and 150 watts in a typical transmission. This is a wide gap in RF power. However, it is a range that places operators between QRP and what many of today’s HF transceivers will output. Some 17 percent use over 150 watts, perhaps up to their license limit. Only 7 percent report that they use QRP levels at less than 10 watts. These responses are not contingent on the mode of transmission.

Turning to the VHF and UHF bands, Figure 2 summarizes the typical power used in Canada. A similar pattern occurs as in HF and six-meter operation. Just under three-fourths (71%) use between 10-150 watts on a regular basis. A small slice, some 2 percent, report over 150 watts. About one-fourth (27%) say that less than 10 watts is what they typically use in these bands.

In both HF and the VHF/UHF frequency bands, only a small proportion say they use amplifiers to reach over the 150-watt RF power mark. There is a small but notable share using what we’ve termed QRP levels in HF (7%). A decidedly larger share use above QRP levels in VHF or UHF bands (27%). For many hams, this is very understandable, given the most popular band of 2 Meters (92%). But operations on HF using a 10-watt definition of QRP are much smaller.

The power utilized in the microwave bands reflects a very different picture. Figure 3 displays two box plots to illustrate. As shown in previous articles on this blog, microwave band usage is a niche activity within Canadian ham radio. Fewer than 10 percent report any activity but these spent quite a bit of time on these frequencies. Likewise, the boxplot in the left panel of Figure 3 illustrates the small number of microwave aficionados who use high power. (This is power in watts without consideration of antenna gain.)

In the right panel, I’ve reproduced the left-hand panel’s data in watts into a logged form to allow readers to more closely see the lower power portion of the distribution. The log of the power in watts places less emphasis in the smaller frequencies at the extreme power levels. The average power usage is 40 watts with a majority under 100 watts of power. This is not the power level emitted from the antenna with is buoyed by the relative gain of the antenna.

I examined these transmitter power reports by province, age group and license class. There was not much meaningful variation in those data apart from the differences in reported activities on microwave bands. In part, this is the limitation I mentioned of the small number of extreme values in the upper power range. The specialization of using high power in the microwave frequencies is a small number of Canadian hams, at least in this survey. It would take a new sampling design to “over sample” hams who are microwave users to get a more reliable estimate of the higher power ranges in use.

In summary, power output in Canadian amateur radio operations tends to reflect the output of the transceiver on HF bands. There is a wide variation in the category but this is a reasonable conclusion. QRP use is a bit smaller than I expected, given the popularity of portable operations (37%). But this reminds us that not all portable operations use low power. There is innovation in a small group of microwave operators. They use a significant amount of power. A later article will examine reported gain in antennas used in this band. As the microwave bands become more routinized in the hobby, these pioneering leaders will have laid a path for others to follow.
