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]
Since 1934 U.S. frequencies above 1500 had been allocated only to four experimental stations that broadcast with a signal 20 kHz wide for "high fidelity." The stations were converted to regular broadcasting with the NARBA frequency move, having already been allowed to choose normal call signs in 1936. [22] W9XBY to KITE (now dark) up 20 1550 1550
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.
The frequency plan was created, which was internationally coordinated at Regional Administrative Conference for FM Sound Broadcasting in the VHF band in Geneva, 1984. [11] Allocated frequencies are still valid and are used in the Czech Republic and Slovakia. The first transmitter was put into operation on 102.5 MHz near Prague in November 1984.
