Books. I love books. Books and reading are a love that was passed down to me from my Mom. When my sister and I were little kids, my Mom would “treat” us with a trip to the local public library. We would bring home stacks of books to read, and I loved every minute of it. A trip to the library, or even better – the book store, was always enthusiastically welcomed.
That habit stayed with me all my life. When I first became interested in Amateur Radio as a teenager in high school, my “bible” was “The Radio Amateur’s Handbook” by Collins and Hertzberg. That book was my constant companion in my teen years and I must have read it, cover to cover, at least a half dozen times. It fueled my wishful dreams of becoming a Ham Radio operator, making contacts with people from all over the world.
I still have that book, and it holds a place of High Honor on my Amateur Radio book shelf.
A few weeks ago, I came home from work to see a rather large package sticking out of my mail box. As I was bringing it into the house, I noticed it was from Schiffer Publishing. I thought that this was kind of odd, as I hadn’t ordered anything from Schiffer. After dinner, I opened the package to find a most wonderful book entitled “Compendium Of Automatic Morse Code”. I couldn’t believe my eyes! The book was sent for me to look over and to offer a review. It is a wonderful piece of work by Ed Goss N3CW. The amount of work and detail that he put into his book is phenomenal.
Granted, this is a niche book. Not every Amateur Radio operator will gravitate towards an edition like this. If you have a love for Morse Code and for the keyers, paddles and other devices that produce it, then this book is for you.
It is exhaustive in its content and detail and everything about this book screams “quality”. From its size, 9 X 11 inches, to the feel of the heavy stock of the pages, to the rich and highly detailed color photography, everything about this book says, “Coffee Table Book for Ham Radio”.
The table of contents includes chapters on
Chapter 1: An Overview of Telegraphy and Early Keys – History
Chapter 2 – Code Readers, Oscillators and Morse Trainers
Chapter 3 – The Electronic Keyer
Chapter 4 – The Single-Lever Paddle (Without a doubt, my favorite chapter!)
Chapter 5 – The Dual-Lever Paddle
Chapter 6 – Portable/Miniature/QRP Paddles (My second favorite chapter!)
Chapter 7: Commemorative Paddles
Chapter 8 – Combination Key and Paddles
Chapter 9 – Convertible Paddles and Paddle Modifications
Chapter 10 – Automatic Mechanical Keys
Chapter 11 – The Elements of Paddle Design
Chapter 12 – Paddle Adjustment and Maintenance
Chapter 14 – Telegraph Machines, Keyboard Keyers and Terminals
Chapter 15 – Computer Interfacing and the Internet
And various appendices and a bibliography as well as a list of recommended reading.
Pretty exhaustive, eh? If you’re thinking,”Well really, how much is there to write about on this subject?” I’ll answer that question by saying, “Over 300 pages, as a matter of fact!”
It’s not hard to tell that writing this book was a labor of love for N3CW. It’s one of the best if not THE BEST book to come down the pike on the subject. It has earned an honored place on my book shelf, right next to my beloved Hertzberg and Collins. However, I can tell you that it doesn’t stay on the shelf for long. It has been in my hands a lot and will be for a long time to come.
I would highly recommend adding the “Compendium of Automatic Morse Code” to your Amateur Radio library if you’re as much as a devotee of CW operating as I am. I can see this book as a golden answer to that age old question that every Ham gets asked every now and then ……. “Honey, is there any Ham stuff that you’d like for your birthday? Or Christmas, or Hanukkah, etc, etc, etc.
Thanks to Ed N3CW and Schiffer Publishing for sending me a copy! It was a very pleasant surprise and is appreciated more deeply than you will ever know.

Today’s Sun (artificially-colored in purple) seen at the 211-angstrom wavelength (Extreme Ultraviolet, or EUV), as viewed by the Solar Dynamics Observatory (SDO), by the Atmospheric Imaging Assembly (AIA).
At this wavelength, at a wavelength not seen by the un-aided eye, we observe this full-disk AIA image through the 21.1 nm (211 A) filter. This Extreme Ultraviolet (EUV) waveband is used to monitor active regions in the solar corona.
The image is a ‘false color image’, meaning that observed data are in a range outside of what human eyes can see, so the data are digitally recast into colors that emphasize physically important features. This view is created from data gathered by the Solar Dynamics Observatory (SDO) satellite that flies above Earth’s atmosphere in an inclined geosynchronous orbit.
Emissions captured in this image come from iron (Fe), a trace element in the solar atmosphere that emits Extreme Ultraviolet (EUV) light when heated to temperatures in excess of one million deg K. In the solar corona the temperatures are so high that most chemical elements have lost many of their electrons. Some of the remaining electrons still attached to the atom emit EUV radiation in narrow wavebands or lines.
The 21.1 nm filter (also called channel or bandpass) is dominated by emissions from highly ionized iron: 13 times ionized (missing 13 electrons) iron–Fe XIV. Other ionization levels of iron also contribute. The roman numeral descriptors are consistent with spectral notation: the level of ionization for a given roman numeral is one unit larger that the actual number of missing electrons. Additionally there may be some contribution from hot thermal plasma when solar flares are present. The temperatures associated with this level of ionization is about 2 x 10^6 K.
The bright regions in this image correspond to regions of closed magnetic field loops that trap the hot, emitting plasma. Large bright regions are often called active regions. The dark regions correspond to cooler temperatures and possibly to locations where magnetic field lines open into the heliosphere, and thus, do not trap hot plasma.
With this image, we can monitore active regions.

Latest TEC map from NASA. What is TEC? Total Electron Content (or TEC) is an important descriptive quantity for the ionosphere of the Earth. TEC is the total number of free electrons integrated between two points, along a tube of one meter squared cross section, i.e., the electron columnar number density. Affected by solar activity, Total Electron Content (TEC) describes the total number of free electrons present within one square meter between two points (i.e. between the receiver and satellite involved in measuring TEC).
These maps are also used to monitor ionospheric weather, and to nowcast ionospheric storms that often occur responding to activities in solar wind and Earth’s magnetosphere as well as thermosphere.

Vibroplex “Blue Racer” |
Ever since earning my ticket as a teenager back in ’63, almost all of my on-air activity has been focused on CW … I’ve always loved it.
For my first year on-the-air, I used a nice brass hand key purchased locally for just a few dollars but once I had mastered that and I was just unable to send any faster with it, I purchased a Vibroplex ‘Original‘, for, if memory serves me correct, around $40. I used it exclusively until building a homebrew memory keyer in the mid-70’s and the Vibroplex saw little service for several years.
The Vibroplex ‘Original’ |
Back when I first got on the air there were very few amateurs using keyers. Most used bugs and the remainder used the brass hand pumps. It was very easy to tune across the band and identify any of the locals just by the sound of their fist … like snowflakes, no two were the same. The same went for most stations that were very active. DX or otherwise, one could usually tell who it was long before the callsigns were heard.
So much has changed now with the almost exclusive use of electronic keyers and everyone pretty much sounds the same, which is rather a pity I think.
Once my interest in building vintage-style vacuum-tube transmitters evolved, my interest in bugs was reactivated and over the years I have purchased a few more.
I’ll do anything I can to promote and encourage the use of CW and especially hand-generated CW. That’s why I was excited to read a recent e-mail from W6SFM, posted to several lists that I read, announcing the Bug Roundup!
Reserve the day! Saturday May 20th – Sunday May 21st, 2017
7:00 AM to 7:00 AM Pacific Time (LOCAL)
1400 UTC through 1400 UTC
For more information, to register your station and key for participation, and to help assist in spotting, potentially increasing QSOs, an On-line chat window link can be found near the bottom of Bug Roundup home page located at http://ift.tt/1sK5yx3 We hope to hear you all on the air!
It looks like a fun event and might make another good reason to fire-up your old boatanchors on CW once again. It looks like you can keep track of activity and possibly set up skeds via their chat-window page during the BR.
In any event, my biggest decision will be to choose which bug to use as I have five at last count. I think I’ll be brave and try the Blue Racer but will probably have to dampen it down a bit as they are really quite fast.

Today’s Sun (artificially-colored in red) seen at the 304-angstrom wavelength (Extreme Ultraviolet, or EUV), as viewed by the Solar Dynamics Observatory (SDO), by the Atmospheric Imaging Assembly (AIA).
At this wavelength, at a wavelength not seen by the un-aided eye, we can see the Sun through the 30.4 nm (304 A) filter. This Extreme Ultraviolet (EUV) waveband is used to monitor the chromosphere and lower transition region. It is useful to see plasma and filament activity, including filamet eruptions and coronal mass ejections (CMEs).
The image is a “false color image’, meaning that observed data are in a range outside of what human eyes can see, so the data are digitally recast into colors that emphasize physically important features. This view is created from data gathered by the Solar Dynamics Observatory (SDO) satellite that flies above Earth’s atmosphere in an inclined geosynchronous orbit.
Emissions captured in this image come from helium (He), the second most abundant element in the solar atmosphere. Singly ionized Helium (He II) emits Extreme Ultraviolet (EUV) light when heated to temperatures of ~70,000 deg K. In the upper solar atmosphere the temperatures are so high that most chemical elements have lost many of their electrons. The remaining electron, which is still attached to the atom, emits EUV radiation in narrow wavebands or lines when it is in an excited state.
The 30.4 nm filter (also called channel or bandpass) is dominated by emissions from singly (once) ionized helium which has missing 1 electron–He II. The roman numeral descriptor is consistent with spectral notation: the level of ionization for a given roman numeral is one unit larger that the actual number of missing electrons. The temperatures associated with this level of ionization is range from 6 x 10^4 K to 8 x 10^4 K.
The bright regions in this image correspond to regions of closed magnetic field loops that trap the hot, emitting plasma. Large bright regions are often called active regions. The dark regions correspond to cooler temperatures and possibly to locations where magnetic field lines open into the heliosphere, and thus, do not trap hot plasma.

Here is the current forecast discussion on space weather and geophysical activity, issued 2017 Apr 30 1230 UTC.
Solar Activity
24 hr Summary: Solar activity was at very low levels. Region 2653 (S09W39, Hrx/alpha) produced a long-duration B3 flare at 30/0012 UTC and an associated CME was observed in C2 coronagraph imagery beginning at 30/0236 UTC. Analysis of this event is underway in order to determine if the CME has an Earth-directed component.
Forecast: Solar activity is expected to remain at very low levels throughout the forecast period (31 Apr-02 May).
Energetic Particle
24 hr Summary: The greater than 2 MeV electron flux reached high levels with a peak flux of 15,914 pfu observed at 29/1835 UTC. The greater than 10 MeV proton flux was steady at background levels.
Forecast: The greater than 2 MeV electron flux is expected to reach high levels over the next three days (30 Apr-02 May). The greater than 10 MeV proton flux is expected to continue at background levels throughout the forecast period.
Solar Wind
24 hr Summary: Solar wind parameters reflected a nominal solar wind regime. Solar wind speed varied between 380-407 km/s, total field was steady near 5 nT, and the Bz component of the magnetic field briefly reached -5 nT mid-period. The phi angle was generally negative this period with a transition to a positive solar sector orientation between 29/1615-30/0030 UTC.
Forecast: Solar wind parameters are expected to remain at nominal levels through midday on day one (30 Apr). By late on day one through day two (30 Apr-01 May) a weak enhancement in solar wind parameters is expected as a positive polarity CH HSS moves into geoeffective position. A slow return to nominal levels is expected on day three (02 May).
Geospace
24 hr Summary: The geomagnetic field was quiet under a nominal solar wind environment.
Forecast: The geomagnetic field is expected to be at quiet to unsettled levels throughout the forecast period (30 Apr-02 May) with isolated active periods likely on 01 May due to the influence of a positive polarity CH HSS.

Today’s Sun, seen through a filter of ‘visible’ light (remember: NEVER look directly at the Sun!), as viewed by the Solar Dynamics Observatory (SDO), by the Helioseismic Magnetic Imager (HMI). This image is known as a 'continuum’ image; a continuum image is formed by filtering portions of the visible light part of the spectrum. The SDO HMI is designed to study oscillations and the magnetic field at the solar surface, or photosphere.
The continuum images allow us to track the evolution of sunspots. These images are important as they allow us to better understand the dynamic nature of the solar atmosphere.
