The Evolution of Royal Rife Machines
All true Royal Rife machines work on the same principle. That is, a high frequency radio signal is interrupted or modulated by a lower frequency generator machine, which is generally in the audible or sub-audible range.
There are a lot of methods of achieving this end, and some of the classic methods used through time will be discussed in the next paragraphs, starting with the original Rife unit, and progressing to the latest Royal Rife machines.
The original Rife frequency generator machine as indicated by Rife’s own notes, used vacuum tubes and a circuit called a super regenerative oscillator. If we put it in simple words, this means that a radio frequency oscillator, which was interrupted by a second lower frequency (audio frequency oscillator), generated the composite Rife signal.
In super regenerative terms, the low frequency oscillator was called the ‘Quench oscillator’. Its job was to quench or stop the radio frequency oscillator for about half the time and to allow the radio frequency oscillator to restart and carry on oscillation for the other half. This technology made combining of the two frequencies a simple matter with a minimum of the parts. Super regeneration was used extensively in the 1930s for a very different reason.
The technique was invented by a man named Armstrong for making incredibly sensitive receivers for the very high frequencies and above. In the 1930s, the electronic components were expensive, and to make a radio with one or two tubes which could perform nearly as well as a six tube set, ensured its popularity. The super regenerative technique is still used today for non-critical applications such as garage door openers and remote controlled toy cars and the like.
Today, high quality units are produced by a few companies like Spooky2 and JWLABS. They are a little quite expensive for the reason that high reliability is required. These are standalone machines constructed in a single chassis. They use expensive but very rugged MOS Field Effect Transistors to deliver about 100 watts to the Rife tube.
The tuner is an integral part of the Rife machine unit. To interrupt the radio frequency, these units use a ‘keying circuit’ borrowed from Morse code transmitters as used by the radio operators. This circuit simply keys or turns on and off the carrier to the power amplifier transistor. The lower audio frequencies are generated by a handheld unit which is also used for the royal Rife units mentioned above
