My Amateur Radio Adventures
Low Power Ham Radio
Receiver & the National Company : a collection of documents,
photographs, and articles about the renowned National HRO receiver, the
National Company, James Millen, Jim Lamb, Herbert Hoover, Jr., together with
HRO coil charts in scalable vector format.
A Little Power and a Very Nice Antenna," QRP Quarterly, Volume 62, Number 3 (July 2021), recounts my QRP operation from the 80-foot tall discone antenna at the Titan Missile Museum in Arizona. Copyright 2021, QRP Amateur Radio Club International.
Paragon Paul and the 1921 Transatlantic Test" from The GARzette, The Official Newsletter of the Gwinnett Amateur Radio Society, December 2020 Volume 29, Issue 12.
Only 99 years have elapsed since U. S. amateur signals first spanned the Atlantic. In the grand scheme of things, it wasn't that long ago....
In the Footsteps of the Ancient Ones" from The GARzette, The Official Newsletter of the Gwinnett Amateur Radio Society, November 2020 Volume 29, Issue 11.
In which I try my hand at grinding a World War II surplus FT-243 crystal up to a 40-meter frequency. The photos as this article appeared are practically microscopic. If you'd like to reprint this for your club newsletter, let me know and I can provide the larger format images for your own layout. Also, as printed the photos for figures 3 and 4 are swapped and don't match the captions.
Vacuum Tubes' Last Stand" from The GARzette, The Official Newsletter of the Gwinnett Amateur Radio Society, September 2020 Volume 29, Issue 9.
In 1959, RCA debued a radically new tube architecture, called the Nuvistor. Was this the tube division's desparate attempt to compete with the rapidly evolving transistor?
Why the Sideband Conventions? The Rest of the Story..." from The GARzette, The Official Newsletter of the Gwinnett Amateur Radio Society, August 2020 Volume 29, Issue 8.
Why do we use Lower Sideband (LSB) for 80-meters and 40-meters, but Upper Sideband (USB) for 20-meters & up? It boils down to a quirk of history -- and war surplus.
Internet is a Wonderful Thing!" from WorldRadio, February, 2008.
This story follows a trail that began with my 2007 visit to the RSGB and how
chasing some details of a TPTG transmitter owned by Barbara Dunn, G6YL, the
first licensed female operator in the UK, led to a 70-year old QSO with a ham in
Bit of Radio Row in Brooklyn?" from WorldRadio, December, 2008. This story touches on New York City's
famed "Radio Row" and Leeds Radio, a survivor from the golden age of radio.
The editor omitted my two footnotes. The first credited a quote from Walt
Gezari, N2EEZ, describing Radio Row in its heyday:
The second footnote was for the Leeds Radio web site:
an 'Almost' Wrinkle Finish on Diecast Aluminum" from The QRP Quarterly, Winter 2008. There are lots of procedures for finishing
diecast aluminum. I did a fair amount of research amongst the alternatives
and settled on a pretty simple and straightforward way to get a great-looking
finish for my Hi-mite 20 meter QRP rig.
Lost Dit of Vibroplex History" from QST, February 2009.
This is the story of Edward F. "Buck" Buchanan, United Electrical
Manufacturing, Horace G. Martin, a Wall Street crash, the little town of
Norcross, and the rare Norcross Vibroplex bugs.
Powell Morgan: the Eternal Boy Turns 120" from the ARRL online web
site of 9 September 2009. The author of The Boys’ First Book of
Radio and Electronics (and Second, Third, & Fourth)
inspired many hams in the 20th Century; but there's more to Morgan than
just the Boys' books.
In 1955, Larry Lighthouse and the
publishers of General Electric G-E Ham News announced a contest
for the development of creative crystal set receivers for use in case of
national disaster. Of course, the disaster they most feared at the
time was nuclear warfare between the United States and the Soviet Union.
The contest was called Operation Crystal and here is a little article, "Crystal
Radio to the Rescue," that appeared in The AWA Journal, the quarterly bulletin of the
Antique Wireless Association, January 2010, Volume 51, Number 1.
The original issues of G-E Ham News concerning the contest also may be
found on my web site
I spent a few months scanning every single issue of G-E Ham News for
posting elsewhere on my
web site and in the process developed an appreciation and affection for the
little magazine. My tribute to Lighthouse Larry appeared as "Look
What Lighthouse Larry has this Month" in the QCWA Journal, Fall
2010, Volume 59, Number 3.
In October, 2009, I visited the Canadian
National Warplane Heritage Museum. From that visit came the little
Classrooms - for radio operators", that appeared in the newsletter of
my local club. The museum has a Fleet Fort Model 60K which was a
training aircraft for radio operators. That little aircraft and
the airmen who trained in it deserve remembrance.
How about a bit of fiction? In 2008
I visited a vintage bookshop near Northwestern University. There I
found a stack of 1920s QST magazines and I purchased a few.
The cover story for one issue concerned Don Mix, 1TS, and the 1923
arctic voyage of the schooner Bowdoin. Now it's a radio
ghost story. This file is from my club newsletter, the October
2010 issue of the GARzette.
Whiskey November Papa: A Tale for Halloween
I guess there's something about Halloween that turns me
into a fiction writer.
We have one more setting...
Back to the Future with the AWA relates my attendance at the
2010 conference of the Antique Wireless Association (AWA) in Rochester,
NY, and how a convention such as that of the AWA could serve as a model
for ordinary hamfests as the traditional flea-market trade increasingly
moves to the Internet. This appeared in the November 2010, Volume
66, Number 11, issue of
CQ magazine and is copyright 2010, CQ Communications, Inc.
Another article came out of my trip to
the AWA 2010 conference. This one, "Crystal
Radios are Like Beer," focuses, naturally, on a small selection
of crystal radios that I came across. The article appeared in
The Xtal Set Society Newsletter, Volume 20, No. 6 (November 2010)
and is copyright 2010, The Xtal Set Society.
National HRO Receiver - A Historical Perspective" is my tribute to
James J. Lamb, W1CEI; James Millen, W1HRX; Herbert Hoover, Jr., W6ZH;
and the team of engineers who created the first single-signal receiver
in 1932 and ultimately the National HRO. The article appeared in
QST, January, 2010 (Volume 95, Number 1).
In April, 2011, I visited the Imperial
War Museum at RAF Duxford, just south of Cambridge, England. While
there I came upon the Duxford Radio Society.
Doors is a little story of this adventure! This article
appeared in the QCWA Journal, Fall 2011 (Volume 60, Number 3).
Publications of historical importance
rescued from obscurity and posted on the web for the benefit of all hamkind.

Here is a 55 minute presentation that I did for the 2021 QSO Today Virtual Ham Expo:
