International radio regulation concerns protection from interference, and sharing of the radio frequency spectrum as a resource. The author reviews the early history of radio regulation, its evolution with terrestrial and space radiocommuni...

This paper will concentrate on radio communications receivers. These are normally intended for professional use in maritime, aeronautical and signal monitoring services, principally in the range 10 kHz to 30 MHz. However, they are also used...

The domestic 'wireless set' was the earliest item of electronic equipment to enter the home. Although clumsy and primitive by modern standards, these sets were in effect the test beds upon which much of todays giant electronic industry is b...

Amateur radio is a hobby that encompasses the whole range of communications technology. It has existed since the time Marconi, Hertz and others began their experiments. It is the only hobby that is regulated by the government of every count...

Discusses the history of home wireless construction, covering a time period, from before World War I, up to World War II. The topics covered include: the crystal set era; home construction; wireless magazines; equipment; and wireless entert...

The paper summarises many of the important developments that have taken place in the tuning of radio apparatus, starting with the early work of Oliver Lodge and Guigliemo Marconi. Over the years improvements have been made both to tuning ca...

We give a brief overview of the various phenomena which may he observed in the ELF (extremely low frequency: 3 Hz to 3 kHz) spectral region, terrestrial ELF propagation theory, and discuss applications which make use of the unique character...

The author attempts a brief summary of the history of ionospheric fading from sources beyond the upper atmosphere. The first sources used were discrete radio stars. With the advent of satellite transmissions at altitudes varying from 300 km...

Radiowave propagation, progressively studied and understood during the past 100 years, has been exploited to provide an ever-growing range of radiocommunication services. The laboratory demonstrations of the existence of electromagnetic wav...

Antennas are an essential part of every radio system and they have been in use for more than 100 years. The continual growth of radio has steadily increased the types of antennas in use. Hertz used reflector antennas and loops in his classi...
