Royal Raymond Rife (May 16, 1888 – August 5, 1971) [1] was an American inventor and early exponent of high-magnification time-lapse cine-micrography. [2] [3]Rife is known for his microscopes, which he claimed could observe live microorganisms with a magnification considered impossible for his time, and for an "oscillating beam ray" invention, which he thought could treat various ailments by ...

In closing, I would like to say what most people are talking about as a Rife machine or Rife frequency, is actually a Crane machine or Crane frequency. Rife's original frequencies from his lab notes started at 400,000 Hz and went to 13,000,000 Hz. Crane's frequencies are at 20 to 10,000 Hz, and Clark's Frequencies are from 80,000 to 800,000.
Frequency allocation (or spectrum allocation) is the part of spectrum management dealing with the designation and regulation of the electromagnetic spectrum into frequency bands, normally done by governments in most countries. [1]
The frequency spectrum of a typical radio signal from an AM or FM radio transmitter. The horizontal axis is frequency; the vertical axis is signal amplitude or power. It consists of a signal (C) at the carrier wave frequency f C, with the modulation contained in narrow frequency bands called sidebands (SB) just above and below the carrier.
Shortwave bands are frequency allocations for use within the shortwave radio spectrum (the upper medium frequency [MF] band and all of the high frequency [HF] band). Radio waves in these frequency ranges can be used for very long distance (transcontinental) communication because they can reflect off layers of charged particles in the ionosphere and return to Earth beyond the horizon, a ...
The timeline of radio lists within the history of radio, the technology and events that produced instruments that use radio waves and activities that people undertook. Later, the history is dominated by programming and contents, which is closer to general history.
