New Book: Learning, Living, and Loving Morse Code…
There is a new book from a fellow Morse code amateur radio operator, Chris Rutkowski (NW6V), about “Learning, Living, and Loving Morse Code (in a Digital World).” NICE!
Title: “The CW Way of Life“
Already, I think it rivals any other book on the topic, including “The Art and Skill of…,” or, “The Zen of…”
It is not, however, meant to replace, but to augment, what is available. But, it is a complete guide, including a “work book” section (nearly half of the book?) on how to improve your skill. Really good stuff, but I’m only in one day.

Perfect Straight-Key Morse Code? Can It Be Made Without Machines?
Short Demonstration of Using Ham Radio Deluxe with WSJT-X and FT8 Digital Mode
Ham Radio Deluxe can log your WSJT-X FT8, JT65A, and JT9 QSOs, via the JT-Alert software. This is a demonstration of my use of HRD and Logbook, during an FT8 QSO,today.
As some of you know, I have had some differences of opinion regarding the selection of frequencies chosen by the FT8 creators and advocates. Regardless, I do still use the mode. Here is proof:
Go ahead and share, if you would. And, please subscribe to my YouTube channel, as I will be creating many how-to videos in the near future.

On How NCIS Maligned the Amateur Radio Service
EDIT: Please view the NEW article, in which the FULL VERSION of this video exists.
I’ve been reading some of the chatter regarding the NCIS episode in which they incorrectly portray the amateur radio service. I thought I would make a video (vlog) and express my thoughts.
I use my new headset mic to make the video. If you have a few moments, please check it out, and let me know how the mic sounds.
Of course, share your thoughts on the NCIS thing… thanks!
Yes, the video gets prematurely cut off. The editing software on my cell phone chopped off the ending, and I did not realize it until after it posted the video. I’ll record a follow-up video that includes the ending thoughts, but in a new vlog edition.

Old, But Still Useful!
This old WWII military training video is still useful regarding Morse code:
This is an antique United States Navy Training Film from 1943/1944, in which proper hand-sending of Morse code is demonstrated. The film covers some basic principles and mechanics of manual keying of the International Morse code, as used during WWII.
Amateur (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.
There’s more about Morse code, at my website: http://cw.hfradio.org
For additional joy, here are a few of old films regarding Morse code:
Morse Code – Principles and Basic Techniques (US Army Signal)
(Learn to Send Perfect Morse Code by Hand – Vintage Training Film (Ham Radio / CW))
Vintage 1944 Radio Operator Training: How to Send Morse Code (CW) by Hand
This one is a pretty cool film:
1939 Film: New Zealand Shortwave Communications; Morse code (CW)
I’ve also created a play list, and most of the videos are still online. Once and a while something changes and I have to update the list. Here is the list:

Optical communications – over the horizon (NLOS)
The DX record for communications at optical frequencies is phenomenal these days. There is a growing interest in communications over non line of sight paths (NLOS) using cloud-bounce or clear air scattering. To my knowledge, in recent times experiments are (or are about to start) by F1AVY, VK4EBP , VE7SL and G3XBM (when fit again). I am sure there are others too. Weak signal modes certainly help. I used QRSS3 over an 8.5km NLOS path, but much further has been achieved.

MGM 1939 film: Radio Hams / More than a Hobby
“Radio Hams” do more than play with their machines. They are also invaluable in relaying vital information during times of tragedy and disaster.
Here is a mildly entertaining look at radio hams, those amateurs sending and receiving coded messages during the late thirties when films first dealt with the subject of “radio hams.” In this case, the ham operators manage to be helpful during situations of stress, using their abilities with code to help someone in distress and to seek aid for pilots flying a missing plane.
The humorous ending has the family gathered around the radio listening to someone speaking Chinese while the narrator tells us how impressed the family was to be hearing someone across the world on their radio set.
This little vintage film, a rather more serious film than many of Pete Smith’s other presentations, takes a look at how ham radios can become priceless aids during emergencies. The two stories shown, one dealing with sickness, the other with a missing plane, are bookended by a humorous look at a typical three-generation family’s fascination with their ham radio.
Of course, amateur radio, or “ham radio”, is alive and doing very well, in our modern times. Using satellites, moon-bounce communications, repeater networks, as well as shortwave, mediumwave, and longwave telecommunications technology, amateur radio continues to provide emergency services in times of need, from hurricanes, tornadoes, earthquakes, and even during such times as the infamous 9/11 atrocity. But, amateur radio also breeds invention and experimentation, always at the cutting edge of science. It is a hobby worth investigating, having room for a wide-range of interests. Preppers, science lovers, experimenters, and those with a passion to meet people from all over the world by way of radio waves, all together make up the radio hobby of amateur radio.
