Research an Old License or Callsign.
Recently my local ham club celebrated its 75th anniversary. I took up a small project of trying to trace some of the clubs history. A large portion of that entailed looking up old callsigns, to help piece things together.

QRZ's notes give the history of FCC records and the dilemma. Basically they didn't start to use computers for keeping records till the 1980's. Prior everything was kept on paper. The only publicly searchable database is the 1993 one that QRZ has. has obviously been transscribing old flying horse callbooks. They have a resonably priced subscription service that will give you electronic access to an archive of of old callsign data; 1921, 1954, 1960, 1969, 1977, 1983, and 1995 to present.

If you are looking for some really old data for free, there is a pretty good guide at
These are Google Book and Hathi Trust scans of government publications mostly prior to the creation of the FCC in 1934. At some point, apparently in the 1930's, the U.S. Government stopped publishing call books. Instead, this task was taken up by private publishers.

For many-many years the resource to have was a printed callbook.

The Citizen's Radio Service Bureau (508 South Dearborn St., Chicago IL) published the first issue of Citizen's Radio Call Book 1921 to 1932.

Then in about 1926; The "Radio Amateur Call Book Magazine" were published by Radio Amateur Call Book, Inc., Chicago, IL. These are commonly referred to as the "Flying Horse Call Books" because of the distinctive artwork always appearing on the cover. Later on the Flying Horse Callbook was published by Watson-Guptill Publishing which was a division of BPI Communications. In normal times the books were published quarterly. 1997 marked the end of the printed callbook. From then on it has only existed as CD-ROM form, the work done by contracted by a German firm, "ITfM" - "Information Technology for People." The German firm ended up buying out Watson-Guptill Publication entirely in 2003.

Anyway seeing has how old callbook data really isn't copyright, I decided to scan the ones I had access to when I was researching my clubs history. You can view them on the internet archive here:

I scanned them the best I could, in case someone really wants a project, of trying to convert it all to text and possibly put the info into a database. Because printed call books were only organized by callsign, not by name. One of the problems with converting to text (besides possible OCR errors is that the data was on multiple lines. So you have to script something to look for a possible callsign match to indicate the start of a new record.

Anyway if anyone has any scans or of old printed books they would like to get to me, I'll see to it they get posted for all.


Thanks to Steve (KB9MWR) for this timely resource.  Like Steve, I was beginning a search for someone's old amateur radio callsign and was having some difficulty finding it.  Steve lists some useful links to help further your search for an old ham callsign or for a long-forgotten club call.  For more information, visit Steve's blog:  A very helpful article.

G5RV Multi Band HF Dipole Antenna. Post #1555.

If you can't see the video, please insert this title URL into your browser search box: This well-produced and richly illustrated tutorial on the classic G5RV HF Dipole Antenna was presented to the Brandon Amateur Radio Society in Brandon, Florida in 2017 by Bernie Huth (W4BGH).  Bernie does an excellent job of  explaining the pros and cons of this popular HF antenna from the late Louis Varney (G5RV).  Although Varney envisioned his design primarily as a 3/2 wavelength antenna for the 20 meter Amateur Radio band, radio amateurs have used the antenna for multiband use.  The G5RV is an excellent choice for the 20 meter band.  Performance on other HF Amateur Radio bands is good enough to qualify as stand alone HF antenna if you can only erect one HF antenna.

Amateur Radio Bicycle Mobile Setup. Post #1554.

If you can't see the video, please insert this title URL into your browser search box: Here's a way to use Amatuer/Ham Radio while you work on shedding a few pounds in useful exercise.  Why not equip your bicycle for 2 meter/70 cm mobile operation? In this short, well-made video, "taverned" shows us how he used a mag mount antenna, a simple C clamp, and a basic ground system to convert his mountain bike into a mobile station.  The project is straight forward, simple, and gives you emergency communications while you peddle down the road.

An 80-Meter Vertical Helix

Like many amateur radio operators, I live on a small lot surrounded by neighbors, utility lines, and civic-minded citizens concerned about the "attractiveness" of my community.  Whether by design or outright fear, I've adopted the "stealth" approach to ham radio antennas.  It's the old "out of sight, out of mind" idea applied to amateur radio antennas. The amateur radio press is full of articles describing the struggle of amateur radio operators to pursue their hobby under the burdensome regulations of CC & Rs, HOAs, and other civic minded citizens who object to antenna farms.  So far, my modest verticals, loops, and inverted vees have blended well with the vegetation and trees bordering my small backyard.  Vertical antennas have always been a problem because of the limited space for a radial system.  There are times, however, where a shortened vertical for the lower HF bands (such as 80/75 meters) is necessary where horizontal space is lack
