Amateur Radio Service

For over 100 years, the Amateur Radio Service has set forth rules, defined standards, and allocated frequency spectrum for the purpose of promoting technical investigations into wireless communication systems by duly authorized individuals having non-pecuniary interests in advancing the state of the radio art.

I have been an Advanced Class Amateur Radio Operator since 1983. Amateur Radio Operators are individuals who are tested and licensed by their federal governments. We develop and implement our own communication systems, and provide voluntary communication services for the benefit of the general public when disasters strike and commercial communication systems often fail.

My Amateur Radio Page provides details regarding some of the more interesting accomplishments I've made as an Amateur Radio Operator, including:

My Eclipse Experiment Page describes a very successful LF radio propagation experiment I conducted during the August 21, 2017 Solar Eclipse, and the results that I presented to the first gathering of the HamSCI Ham Radio Science Citizen Investigation Group in February 2018.

I am also a member of the Straight Key Century Club and hold membership number 16486C.



Software Development

I develop computer software as a hobby, mostly for personal use in Amateur Radio Service applications. Over the years, some of my software has attracted the favorable attention of professionals employed in the scientific, research, terrestrial broadcast, telecommunication, aerospace, and wireless networking fields. As a consequence, some of my software has been adopted for use at some very prestigious organizations such as NASA, the Goddard Spaceflight Center, the European Space Agency, Stanford and Cornell Universities, the California Institute of Technology, Steven's Institute of Technology, NBCUniversal, Alcatel-Lucent, Space Data Corporation, the University of Massachusetts, the U.S. Army, and the U.S. Naval Academy, just to name a few.

My Software Development Page provides general information on some of my most popular software products, including:

I prefer writing software using the 'C' programming language under a Slackware Linux operating system environment, thereby making my software compatible with all POSIX-compliant computing environments. When writing code for PIC Microcontrollers, I use Assembly Language.



Hardware Development

My exposure to the world of electronics began at a very early age and it remains a major passion in my life. I possess Associate's and Bachelor's Degrees in Electronics Engineering Technology, as well as an Advanced Class FCC Amateur Radio Operator's License and a Commercial FCC General Radiotelephone Operator's License.

I develop electronic hardware as a hobby, mostly for personal use, and generally with an aim toward Amateur Radio Service applications. Details of some of my published hardware designs can be found on-line:

My FMT Methodology Page provides an overview of instrumentation I developed for making precise, long distance frequency measurements and Ionospheric Doppler shift studies.

My First Generation Slow-Scan TV Page describes my introduction to Slow-Scan Television at an early age, and my more recent design of a TriplePIC SSTV Video Scan Converter for the purpose of viewing vintage SSTV video images on a standard NTSC video monitor.

Additional technical articles I've authored on-line may be found through the following links:



Publications

In addition to creating and authoring SpaceNews for more than 13 years, I have had a host of technical articles published in a variety of books and periodicals, including:

I have also served as a regular columnist for Satellite Times magazine, as a cover model for CQ-VHF magazine, and as a guest on several radio programs. My SpaceNews newsletter was read by Cosmonaut Musa Manarov while living on the Russian space station Mir in 1991. The design of my ATV Modulator is described in The ARRL Image Communications Handbook, by Dr. Ralph E. Taggart, WB8DQT.



"John-A-Tronix"

From a very early age, long before the "Maker" movement started gaining traction, I have been creating ideas, bringing them to life, and sharing what I have gained through my experiences with others. A few examples:
