Where does the radio phrase "Ham" originate?

There are a number of definitions given, so you takes your choice. This is my preferred version: The word HAM is derived from the initial letter of each of three pioneers of Radio;

Hertz, Armstrong and Marconi.

Heinrich H ertz helped to develop the theory of electromagnetic waves. Hertz even detected them with a spark.

Edwin Howard Armstrong started as a teenager as a radio amateur and was a star student in electrical engineering at Columbia. In 1912 he figured out how to improve the audion dramatically. In 1914 Armstrong demonstrated his idea to the Marconi Company, where David Sarnoff realized its importance.

Guglielmo Marconi used sparks to create radio waves. He grew up in Italy the son of an Italian father and a Scotch-Irish mother. In 1899 Marconi successfully linked England and France across the English channel (where there was already a cable)--more significant was transmission from ships. Marconi transmitted signals across the Atlantic in 1901.

Frequencies and Transmitting Modes

Radio Amateurs or "Hams" use a number of different frequencies for communications, these frequencies are allocated by the FCC for amateur use.

Hams may operate from just above the AM broadcast band to the microwave region, in the gigahertz range.
Many Ham Bands are found in the frequency range that goes from above the AM radio band (1.6 MHz) to just above the citizens band (27 MHz).

During daylight, 15 to 27 MHz is a good band for long-distance communications. At night, the band from 1.6 to 15 MHz is good for long-distance communications. These bands are often referred to historically as short-wave bands.

Unlike frequencies used by FM radio stations and TV stations, which are line-of-sight and therefore limited to 40 or 50 miles, short-waves "bounce" off the ionosphere from the transmitter to the receiver's antenna. The higher the frequency, the "shorter" the wavelength.

Forest of Dean Amateur Radio Club

Due to a resurgence of licensed Amateurs in the area over the past few years, a small group of us headed by Adrian-M3TVF, met on a monthly basis to discuss the possibilities of forming a Forest of Dean Amateur Radio Group. We have now formed a group and we are delighted to report that we are now up and running following a successful first meeting..

We are looking for people with interests in Amateur Radio, (licenced or not), Electronics, Weather Satellites, Space interests and anything connected with Communications to become members. Young people both Male and Female with an interest in becoming Radio Amateurs will be made very welcome.

If you feel that you can contribute to the club in any way and wish to become a member, or for details about what was discussed at the meetings and dates of future meetings, visit the FODARG website Forest of Dean Amateur Radio Group
