New International Call Sign Handbook 5th Edition Now Available on Amazon

Ask any radio monitor what information they consider important during any monitoring session, and usually two items will top their list: frequencies and call signs. If you can hear activity on a particular frequency, unless you can fully identify the participants transmitting on that frequency, you can’t fully appreciate or document the traffic you are hearing.
With millions of radio stations furnishing a variety of communication services throughout the world, it is necessary that their transmissions carry distinctive call signs or identifiers. Call signs have a four-fold purpose: They may identify the nationality of the station, the agency operating a particular station, the type of station, and the identity of each individual station being heard on the monitored frequency.

The need for station identifications/call signs can easily be illustrated here in the United States, which leads all other countries in the use of the radio spectrum, that now has some 85 different kinds of radio services operated by the government, military and civilians entities, providing air, sea, land and space communication services. There are hundreds of thousands of stations on the air and call signs and other forms of identification help the radio monitor sort through the various stations that are heard.

A call sign is defined as any combination of alphanumeric characters or phonetically pronounceable characters (trigraph), which identifies a communications facility, a command, an authority, an activity or unit. To aid the radio monitor in their listening endeavors, the International Call Sign Handbook series of books/e-books has been published.

Teak Publishing is pleased to announce their latest Kindle e-book -- the fifth edition of International Call Sign Handbook by Amazon Bestselling author Larry Van Horn, N5FPW. This e-book represents the most comprehensive collection of military and government station identifications ever published for the radio listening hobby. It is the result of year’s research, study and monitoring the HF/VHF/UHF radio spectrum, by the author. Many different radio monitoring disciplines have been used to compile the listings in this book. If you monitor the HF, VHF or UHF radio spectrum, there is something in this book for you.
The information presented in this book has also been gathered through personal 

correspondence, material published in the former Monitoring Times magazine, various radio publications, newsletters, public domain government and private internet web sites, but most have been gathered the old fashioned way via on-the-air monitoring. In addition, we have received generous support and contributions from many individuals in the radio hobby.
In addition to international and military/government tactical call signs, other types of identifiers such as Automatic Link Establishment (ALE) and Mode-S aircraft addresses have been included in this e-book. There is a chapter that had basic introductory material, as well as chapters devoted to call sign / words used by the Department of Defense including the US. Air Force, U.S. Army, U.S. Navy and Marine Corps. There are sections that cover the various Military Auxiliary Radio Services and the U.S. Air Force Civil Air Patrol auxiliary service.

There is also a chapter that covers call signs and ALE identifiers for the U.S. Coast Guard service. Sections in that chapter include a Coast Guard aircraft fleet list, miscellaneous U.S. coast guard calls, and also their international call signs.
