The BCX Ultra Rife frequency generator is produced in the U.S.A. by Whitman Technology, which has been manufacturing Rife frequency instruments for over 26 years. The BCX Ultra supports multiple waveforms and utilizes, among other things, a radiofrequency (RF) carrier wave, crystal control and gating. This working model is in excellent condition and features all of the original components—i.e., handheld glass plasma ray tubes, metal hand cylinders, metal foot plates, power cable and power adapter—including the Frequency and Procedural Manual and the Universal Frequency List. The BCX Ultra also supports the use of adhesive gel (“TENS”) electrodes, which are readily available from third–party vendors online, as well as external LEDs and other accessories, such as the BCX Ultra Vortex Modulator.
