Specially designed to allow square wave modulation of up to 42,000 Hz when using standard computer sound cards.

The SSQ-2F Controller generates a square wave modulated 3.1 MHz RF signal which may be sent to an RF amplifier to drive a Rife Plasma tube.

Overview -

• This SSQ-2F Rife System Controller is a control system that allows full implementation of the Jeff Garff Rife "Big Sweep" protocol using a 3.1 or 3.3 MHz carrier combined with a wide-range audio frequency sweep. For further information about this, please see: http://rifevideos.com/dr_rife_and_philip_hoylands_3.3mhz_sweep.html and http://rifevideos.com/pdf/a_history/the_rife_machine_report_a_history_of_rifes_instruments_and_frequencies.pdf
• The SSQ-2F Rife System Controller allows the use of a standard computer sound card, an MP3 player, a CD or a DVD player instead of an expensive frequency-function generator to generate the audio signal.
• A standard frequency or function generator may be used as the audio frequency source, if desired.
• Depending on the operating mode, the Rife System Controller will accept sine, square, or triangle waveform audio signals.
• A wide range of audio input levels may be used.
• The 3.1 MHz RF carrier may be square wave duty cycle modulated between 0 to 100%.
• The square wave modulation is selectable in two separate ranges; 0 to 50%, or 50 - 100%.
• The plug-in carrier oscillator module may easily be changed by the user to obtain a custom carrier frequency.
• The Controller can be set to use the modulation frequency directly, (1 X Mode,) or it can be set to double the modulation frequency, (2 X Mode.)
• Connections are provided for optional square wave duty cycle metering using either a user provided meter or the accessory M1D meter.
• Connections are provided for an external audio gain potentiometer using either a user provided potentiometer or the accessory R2 potentiometer.
• The level of the modulated RF output signal is user selectable, and may be set to 5 volts for directly driving a MOSFET amplifier, or 12 volts for driving other devices.
• This is a professionally manufactured etched printed circuit board with 3-ounce, tin plated, copper traces and plated-through holes. All parts are high-quality through-hole components.
• Electrolytic capacitors are rated for operation at 105° C for reliability.
• Resistors are high stability carbon or metal film, 5% tolerance.
• The active devices are socket mounted for easy, solder-free replacement if necessary.
• The SSQ-2F Controller Board is available assembled and fully tested, or as a do-it-yourself kit. A parts kit,and the printed circuit board, are also available.
• The SSQ-2F v1.41 Controller Board may be battery operated if necessary - power consumption is only 1.5 Watts.
• Screw terminals are provided for all connections to the Controller Board - there are no wires to solder!
• Heat sink used on +12-volt regulator for stability in high temperature environments when using a power supply greater than 18 volts.
• 1-year warranty against manufacturing defects.

Specifications:

Power:

• Power Requirements: +15 to +30 Volts DC @ 100 mA, filtered, unregulated.

Input Audio Signal Waveform:

• Sine, triangular or symmetrical or asymmetrical square wave.

Modulation Modes:

• 1x Mode - The modulation frequency equals the input audio frequency using sine, triangle or square waves.
• 2x Mode - The modulation frequency equals TWICE the input audio frequency using sine or triangle waves only.

Carrier Frequency:

• 3.1 (standard) or 3.3 MHz. Frequency to be specified at time of order.
• Customer requested frequencies are available on special order.
• The plug-in carrier oscillator module may easily be changed by the user.
• With the appropriate oscillator module inserted in the Controller Board, carrier frequencies from 0.5 MHz to 15 MHz may be obtained.

Modulation Frequency Ranges - 2x Mode:

Input Audio Frequency Range in 2 X Mode @ 40 - 175 mv p/p input level with a Sine or Triangle Wave input signal:

• Low - 40 Hz
• High - 30,000 Hz at maximum audio gain, or 60,000 Hz at minimum audio gain.
• This will square wave modulate the carrier over the range of 80 to 60,000 Hz or 80 to 120,000 Hz.

NOTE: In the 2x mode, using a sine or triangle wave audio input, the output of the Controller Board will maintain a 50% duty cycle ratio to within 10% or less across the input frequency range of 40 to 30,000 Hz at maximum audio gain, or 40 to 60,000 Hz at minimum audio gain. This allows unattended operation of the equipment without the need for constant audio gain adjustments when using an audio sweep signal generated by a computer sound card. It is necessary to maintain a low source impedance and a constant voltage as the audio frequency changes during the sweep.

Modulation Frequency Ranges - 1x Mode:

Input Audio Frequency Range in 1x Mode, @ 50 - 140 mv p/p input level with a Sine or Triangle Wave input signal:

• Low - 4 Hz
• High - 200,000 Hz at any audio gain setting.
• This will square wave modulate the carrier over the range of 4 to 200,000 Hz

• Usable frequency range from 4 to 400,000 Hz with increased audio input level.
• This will square wave modulate the carrier over the range of 4 to 400,000 Hz.

Modulation Frequency with a Square Wave input signal of 50 - 75 mv p/p and minimum audio gain:

Note: Square wave audio is usable in 1 X Mode only, and a 50% duty cycle is output by the Controller Board.

• Low - 75 Hz
• High - 200,000 Hz
• This will square wave modulate the carrier over the range of 75 to 200,000 Hz.

• Usable frequency range from 50 to 600,000 Hz with increased audio input level.
• This will square wave modulate the carrier over the range of 50 to 600,000 Hz.

SSQ-2F Waveforms

3.1 MHz RF Carrier Oscillator

Lower Trace = 6 KHz audio sine wave input to the SSQ-2F

This is the non-frequency doubled mode of operation of the SSQ-2F.

Lower Trace = 6 KHz audio sine wave input to the SSQ-2F

Upper Trace = Modulated 3.1 MHz RF Carrier output, modulated at a 12 KHz rate with a 50% duty cycle square wave.

This is the frequency doubled mode of operation of the SSQ-2F.

Lower Trace = 194 KHz audio sine wave input to the SSQ-2F

This is the frequency doubled mode of operation of the SSQ-2F. Note that individual cycles of the 3.1 MHz carrier may be seen in the upper trace. Also note the very short rising and falling edges of the modulated 3.1 MHz RF carrier signal.

Same as the above picture, but zoomed in to show the very fast edges of the modulated 3.1 MHz RF carrier signal.

Lower Trace = 155 KHz audio sine wave input to the SSQ-2F

Upper Trace = Modulated 3.1 MHz RF Carrier output, modulated at a 310 KHz rate with a 10% duty cycle square wave. This is the frequency doubled mode of operation of the SSQ-2F. Note that there is only one cycle of the 3.1 MHz carrier present in the output. This illustrates the high accuracy of the modulation circuitry of the SSQ-2F.
