Comparing the weak signal performance of a WBR Regen with a K2
The WBR seems to get a bit of a bad rap with some people for it’s sensitivity. Based on my experience, this design does seem to be fairly deaf on AM, but the sensitivity on SSB/CW is fine.

SOTA Super Activation
The aim of the event is to get as many Summit to Summit – “S2S” – contacts as possible. The summit contacts can be between North America and Europe or within the regions themselves.

Saturday’s 630m Crossband Night – Reminder


This is a reminder of tomorrow's '630m activity night'. Highlights of the evening will see six different Canadian stations seeking contacts with other amateurs in North America via the 'crossband mode' as they call CQ on 630m CW but listen for replies on their announced (QSX) HF frequency. As well, there will be an increased level of on-air activity from many of the U.S. experimental stations, as they beacon or work each other on various modes including CW and JT9, the WSPR QSO-mode. The experimental stations are also seeking your reception reports.

More information may be found here regarding the activity night, including a detailed list of participating Canadians along with their respective transmitting and QSX HF listening frequencies.

As is often the case, old 'Sol is threatening to throw some junk our way over the next day or two, right on time for our event but please don't let that stop you from participating as often this can actually enhance propagation, especially on the north-south path.

We hope to see many of you tomorrow night!

Yet another Arduino clock

Does the world need more Arduino clocks? Maybe not.

But I needed another Arduino project as I had made a K3NG morse keyer. I love this keyer because it is unique in supporting a display where you can see what you send. But I wasn’t using the morse keyer all the time, so I wanted the hardware to serve two purposes. That’s the excuse for also making a clock.

Its main features are:

The hardware for the K3NG keyer includes a speed pot and a memory bank selector (to the right) as well as four push buttons on top for selecting memories. The pot now controls the intensity of the display, but the bank selector switch is not used. Of the four push buttons, only button 1 is used. With it one can toggle the clock through various displays as shown below.
Local time, solar and lunar state
Line 1: Local day, date, time
Line 2: Sunrise, maximum solar elevation (actual solar angle during the day), sunset
Line 3: Civil dawn, local time at maximum solar elevation, civil dusk
Line 4: Lunar phase, arrow showing that it is rising, days since new moon

UTC and position display
Line 1: UTC time, locator
Line 3: latitude, longitude
Line 4: Altitude, number of GPS satellites
Dual time display with local time, UTC time, and locator
What I would like to have as well is an indication of lunar visibility at the actual location with azimuth and elevation for the moon. So far I haven’t had success in finding a suitable Arduino library for that, but I’m hoping that a reader of this blog may help me.

Head Copying CW

There's more to using Morse Code than Learning Morse Code

It's been about 18 months since I started learning Morse Code in order to use it for making CW contacts in amateur radio.  Learning the code allows you to recognize the letters, numbers and punctuation but it's akin to when you learned your "letters" when you were a child.  Knowing the alphabet is just the first step to "reading".  So it is with learning Morse Code.  



When I started making contacts using CW it was fairly formulaic. I even had my QSOs written out with regard to what I was planning to send and what I expected to hear during each exchange. 

But then my copy and sending speed increased beyond 17-19 words per minute and I could no longer type or write down what I copied fast enough to comprehend and I began to head copy.

Head Copying

Head copying is when you stop transcribing what you hear and listen to it as you would a conversation and only take notes on salient points.  This was a big step for me and it has been a difficult transition.  

Using Morse Code to communicate at speeds faster than it can be written straddles the weird place between hearing and reading.  We learn morse code by its sound but at slower speeds, say below 30wpm what we are "hearing" is letters, not words so we are having to buffer those letters in our head to spell words.  When we "listen" to someone speak we are not hearing them speak letters but complete words, when we "read" our brains are not looking at individual letters but at complete words.  When we hear Morse code at 20-25 wpm we are hearing very slowly pronounced words and it is a new skill that has to be learned.

This skill is necessary for ragchewing.  A ragchew is a long QSO between two amateur radio operators. This is generally what amateur radio operators are doing on the radio when they're not contesting, ...


How to practice for a ragchew

So after you learn the code, how do you learn to use it in a conversation?  

I struggled with copying ragchew QSOs at 20+ words per minute for most the spring and early summer of 2016.  Just listening to QSOs alone wasn't cutting it for me.  During my lunch time at work I began regularly using my CW training application on my phone to send the top 500 words at 25wpm and it has been a big help to me.  

I had to learn the skill of not just recognizing letters but holding what I was hearing in my brain long enough to turn it into a word and just as importantly not to get hung up on a word that I couldn't immediately recognize but let it go and pay attention to the next.  To me, this has been a bigger learning curve than recognizing the alphabet and numbers at speed.

In addition to learning to buffer the letters until they form a word I must also keep the slowly accumulating set of words in my head until it forms a sentence or makes sense as to what is being communicated.  
THIS IS COMMUNICATION with Morse Code and it is different than anything else we are familiar with so treat it as learning a new skill.

Now if all you are trying to do with CW is contests, you don't need this skill.  You just need to be able to copy a call and whatever designators are sent after it for the contest rules (state abbreviation or a contest number or grid square) and get it copied into your logging program.  But if you want to communicate at speeds above 20wpm you will need this new skill.

Next steps

After you've practiced with machine sent top 100 or top 500 words you'll still need time copying actual QSOs because more often than not, most operators you will communicate with have lousy spacing and run their words together or use so many abbreviations that you'll have to learn to hear the abbreviations as new words.  When I work an operator who runs things together I'll first try to really exaggerate my word spacing during my exchange to give them a hint and if that doesn't work I ask them put more space between their words.  Some will comply, but some folks just don't seem to know how to leave space so I'll catch what I can, politely respond to what I could understand and then move on.

So if you're getting discouraged when you reach a wall of comprehension, try the steps above and with time I think you'll find your comprehension during a ragchew improving and it will take you to a new place in the hobby.

That's all for now

So lower your power and raise your expectations... and put extra space between your words!
