I have decided to learn CW. Why? Because I want to, not because I have to.  Yes I am one of those no-code hams!

Most of this blog post is aimed at newer hams. If someone is thinking about trying to learn CW, I hope this post might help motivate them to go for it and give it a try.

Since I became a more active ham a couple years ago, from a non-active ham, I have thought it would be nice to have a very small portable battery powered radio, and easy & quick to deploy antenna and make some QSO’s when and where I can.

The next question, once I decided to learn CW, was how to learn CW? I know in the past, people used to use cassette tapes, learning at 5 wpm (words per minute). I looked online and found that the “tapes” can still be purchased, but now they are on CD instead of tapes. From the reviews that I have read, the content has not been updated but simply copied on to CD format. So it’s the same lessons that existed in the 60’s, 70’s, 80, etc, just in a little newer delivery format. My goal isn’t 5 wpm. It’s higher. More like the 20 wpm range someday. That then leads to some “newer” methods of learning. The “Koch” method is very popular. It starts with two characters, sent at 20 wpm but with more space between the characters, making the effective overall speed slower but still with faster character speed. The key is learning characters at a faster speed, introducing another letter when you learn the first two. You keep adding letters until you eventually have them all learned. There are many web sites and programs that use this and other methods. There are also a lot of phone apps that people use to learn. A friend of mine learned CW using these apps, and I sat with him on Field Day in 2013 as he worked without a microphone, only CW. He didn’t even bring his microphone to Field Day! He now works CW almost exclusively.

After further research I came across The CW Operators Club web page, http://www.cwops.org.  I found that they have a CW Academy with 3 different levels. Level I is for beginners with no CW experience and Levels II & III are more advanced working on increasing speed and other things. I decided to enroll in their Level I beginner class. I signed up on their web site and weeks later, I was confined for the Level I class that started in January ’16, a few weeks ago. I am now 5 weeks through an 8 week class. The class meets twice a week, using Skype. There are five students in my class, which is lead by an experienced instructor. Homework consists of using a web based CW training program, for receiving practice. Assuming you have a key/paddle or something to send with, there are sending exercises as well.  The curriculum introduces the letters, much like the Koch method, at a 20 wpm pace, but in a different order than the standard Koch trainers. The first session consisted of four letters, and words using those four letters. If you would like more information their web site is: http://www.cwops.org

Is it working? So far it is working. Five weeks into the class, I now know the whole alphabet, the numbers 0-9 and a few punctuation characters. I say “know” them, but I am not very good at receiving yet. I miss a lot of characters when I try to listen so a real QSO on the air. Like learning anything like another language, it’s going to take some practice to get better at listening in real time. I have recorded a couple QSO’s from a websdr.org station and when I repeat it multiple times, I can figure it all out. Considering 5 weeks ago I didn’t know a single letter, I am making progress.

I’ll continue attending class, and practicing. I’ll post again later when I make some more progress and someday pretty soon, I’ll get in the air and attempt a real QSO!

Until then    – – . . .   . . . – –

PS   “- – . . .   . . . – -”  is morse code for “73” in case you wondered!

Under most circumstances and on most bands, a contact between VE7 and VE3 would not be considered 'exciting' or 'challenging' ... but Saturday night's CW QSO between myself and Mitch, VE3OT in London, Ontario, met both of these criteria, as it was done on our new 630m amateur band on 475.0 kHz. As such, it represents the first-ever interprovincial contact as well as the furthest contact (2031 miles) between two Canadian stations on the 630m band. As usual, there's more to the story ...

Both Mitch and myself had been alerted to the excellent propagation earlier in the week, when VE3OT's CW beacon had reached S9 levels here for several hours on two consecutive nights ... but any late-night QSO attempts would have to wait until the weekend, when having to get up in the middle of the night would not conflict with Mitch's workweek schedule.

Our first attempt, late on Friday night and 3A.M. for Mitch, found that conditions had deteriorated from midweek's enhanced propagation and the low signal levels, combined with some unseasonal lightning noise, resulted in rescheduling for another shot on Saturday.

Late Saturday night found the band much quieter and propagation much improved, but not as good as it had been earlier in the week ... somehow Murphy always seems to have a hand in pre-planned events, and it's never a helpful one. Mitch's beacon signal was readable here but had a deep ten-minute fade cycle with a short-lived peak before fading out to nothing.

Hoping to take advantage of one of the peaks, we began short two-by-two calls from both sides shortly after 0700Z. I eventually heard Mitch fade up and sending a '339' signal report but my response and '559' signal report to him went unanswered as he had faded away again. I continued the short calls, along with my signal report to him and on the next peak heard him responding with 'RRR and 'QSL'! This time his signal continued to build and we had several short exchanges, with Mitch upgrading my RST now to '549' and with me advising of his stronger '569' signal. As the fade cycle took its grip once again, we exchanged our '73's', 'TU's' and 'SK dit-dit's', while we still had the opportunity ... I can't speak for Mitch, but for me it was a truly exciting contact and one I'll not soon forget.

LF / MF station at VE3OT

I'm sure the opportunity to work again will present itself fairly regularly as we both know that Saturday's conditions were not the best. It will be interesting to try again when signal strengths reach the levels previously heard during the week.

For those of you that worked VE3OT during the recent 630m crossband event, Mitch has put together a very special QSL card!


As the solar cycle winds down, the 'good' nights will happen more often, as will the truly 'great' nights. Hopefully there will be more Canadians on the band to take advantage of what lies ahead.

Hopefully the U.S.A. will soon have the band as well, which will really spark nightly activity. What is really needed right now is more Canadian activity, especially in the western provinces, where nightly CW contacts could be readily made. Time to reach for the solder iron! There are several VE7's, and one VE3, waiting and wanting to work you!

Every amateur radio operator is attracted to different aspects of our diverse hobby. For Cliff Batson, N4CCB, of Nashville, Tennessee, it’s QRP — making radio contacts with 5-watts or less.

“I’m not an expert, but I have quite a bit of passion and enthusiasm for QRP. There’s just something magical about being able to make contacts using less power than a nightlight,” says Batson.

Batson started a video blog called QRP School late last summer and recently added his twentieth episode. He’s already covered topics like using a deploy-anywhere vertical HF antenna (below), solar power operations, building a computer-to-CW interface, bringing your gear along on vacation, and many more. He says that he hopes to add even more QRP-related videos soon.

“Ham radio is a big hobby, and there’s room for all of us to enjoy whatever we enjoy, while letting others do their own thing,” he says.

Here is this week’s space weather and geophysical report, issued 2016 Feb 15 0238 UTC.

Highlights of Solar and Geomagnetic Activity 08 – 14 February 2016

Solar activity was low from 08-11 Feb. The largest C-class event during that period was a C8/1f observed at 11/2103 UTC from Region 2497 (N13, L=087, class/area Eac/250 on 12 Feb) with associated Type II (est. speed 483 km/s) and Type IV radio sweeps. A CME was visible following this event and is anticipated to arrive at Earth early on 15 Feb. Solar activity was moderate from 12-14 Feb with Region 2497 producing an M1 flare each day. No other Earth-directed CMEs were observed.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels during the period.

Geomagnetic field activity began the week at minor storm levels due to effects from a co-rotating interaction region (CIR) ahead of a CH HSS. Predominately quiet to unsettled levels were observed for the remainder of the period with isolated active periods on 09, 11 and 12 Feb associated with extended periods of negative Bz.

Forecast of Solar and Geomagnetic Activity 15 February – 12 March 2016

Solar activity is expected to be at very low to low levels with a chance for M-class flares from 15-17 Feb. Activity is expected to decrease to very low levels with only a chance for C-class flares from 18-29 Feb as Region 2497 moves beyond the west limb. Low levels are anticipated once again on 01-12 Mar as well as a chance for M-class flares with the return of Region 2497.

A slight chance for a proton event exists at geosynchronous orbit from 15-17 Feb due to the flare potential and position of Region 2497.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal to moderate levels for the majority of the period. High levels are likely on 18-20 Feb following effects from a CME and a subsequent CH HSS.

Geomagnetic field activity is expected to reach minor storm levels on 15 Feb due to effects from the 11 Feb CME. Quiet to active conditions are expected on 16 Feb as CME effects subside. Minor storm conditions are likely again on 17 Feb as a recurrent negative polarity CH HSS becomes geoeffective. Quiet to unsettled conditions are expected with isolated active periods possible on 18-20 Feb as CH HSS effects continue. Mostly quiet conditions are expected on 21-29 Feb. Quiet to unsettled conditions are expected from 01-03 Mar due to effects from a positive polarity CH HSS. Mostly quiet conditions are expected for the remainder of the period with unsettled to active periods possible on 06-07 Mar and 11 Mar as two sequential small recurrent coronal holes affect the field.

I have been using small footprint computers in ham shack for a while. It started with the Dell Zino. Always a bit under powered, but enough to get the hamming done. The latest computer driving everything was one of those barebones models that was the size of a shoe box. The first sign of decline was when the fan kept getting louder and LOUDER. The the drive (500GBs of SATA) then decided to give up the ghost.

An immediate lesson learned… back up my log. I have been good at uploading my logs (almost daily, when on the air) to LOTW, QRZ.com, and eQSL. But I would only export that days contacts, consistently replacing the previous days exported log.

I choose not to abandon the small footprint computer and went back to the Shuttle. Newegg.org was my one stop shopping:

The case and motherboard: Shuttle XH81 Intel Core i7 / i5 / i3 / Pentium / Celeron 65W Intel H81 1 x HDMI Barebone system
– small form factor, fits neatly underneath monitor.
– 2x RS-232 connections on the back. Perfect for connecting to the Elecraft amp and tuner.
– Plenty of USB connections

Intel Core i7-4770S Haswell Quad-Core 3.1 GHz LGA 1150 65W BX80646I74770S Desktop Processor Intel HD Graphics
– not the fastest, but fast enough.
– comes with a super quiet fan.

Transcend JetRam 8GB 204-Pin DDR3 SO-DIMM DDR3 1600 (PC3 12800) Laptop Memory Model JM1600KSH-8G
– I got two DIMMs to keep things moving… 16GBs = snappy!

SAMSUNG 850 EVO 2.5″ 250GB SATA III 3-D Vertical Internal Solid State Drive (SSD) MZ-75E250B/AM
– Good bye disk, hello solid state. Faster. Silent.

The actual build was plug and play. The Shuttle line has come a long way since my last experience with their product. I think these specific computers are designed to operate older types of technology (hint…. 2x RS-232 connections?) which works great with most amateur radio needs.

The next step was loading the OS. LiLi USB Creator is my go to solution for installing linux when I don’t have an optical drive (which is more often the case). This allows you to load the OS through booting directly from the USB stick.

The linux flavor of the day: Mint with the MATE edition. I was an Ubuntu man until Unity. Then made the jump to Mint. The OS loaded without issue and I was off and running.

Amazingly enough, I was able to install TQSL-2.2. In the past, I have been able to install TQSL from the Software Manager. But this has been an older version of TQSL. The newer versions ALWAYS gave my problems with dependency issues during attempted installs. I stayed with it this time and finally got it working. Phew!

The install of fldigi went smoothe, but configuring it to work with my Elecraft K3 was giving me fits. In my past setup, I’ve always used hamlib for rig control and the trick was just finding which USB number was being used for my USB Microham III. But this time, the USB Microham III was identified by name as a choice. Great! But it didn’t initialize. I tried USB0 (…. nothing), combed over the results of lsusb…. not… working. After some intense Googling, I ran across a command I had never seen before:

sudo adduser [username] dialout

Dialout!? Who knew? But that did the trick.

Now, here is something funny. We all have our junk boxes. As hams, we are pack rats. We hang on to stuff that has no current use, but may someday. I had a box RS-232 cables. When Fall Cleaning swept through the ham shack, I looked at the RS-232 cables. I am really going to need 15 RS-232 cables ranging in length between two and 15 feet? The box headed to the dump.

Now, with my growing K-Line, I can use Elecraft software (linux versions available) to monitor data from the amp and tuner. But the connections are serial. SERIAL. I turned the ham shack upside down and not an RS-232 cable to be found. I really don’t want to have to actually go out and BUY a serial cable.
