RF PROPAGATION & STANDARDS
In its formative years, radio or wireless, as it was then more commonly known, had very unrefined means of reception and transmission. RF generation and tuning was broad in the extreme in both transmitting and receiving equipment. The principles of antenna resonance were largely unknown. Transmitting used various forms of spark generation which produced such a broad signal and splatter that interference eventually became intolerable.
Practically nothing was known of propagation characteristics at the low frequencies initially used. Even less was known about propagation at the yet untried higher frequencies. Radio Amateurs who were banned to the “useless short-waves” can be proud of the significant role they played in exploring, developing and showing the way in gaining practical use of the high frequency spectrum.
Radio Amateurs over the years have led and continue to be in the forefront of research and development in all parts of the spectrum. Standards play a significant role in their experimental and operating activity. Knowledge of propagation characteristics and propagation forecasting is key ingredient in their communication skills and accomplishments. This page of the MAARC, Inc. Website is intended to serve as a ready propagation, frequency, time and standards reference
by providing convenient access to a few related Websites.
