Unit 1 is tuned by adjusting the choke to about 500 to 1000 cycles apart (this will be somewhere around 22,000 cycles - above human hearing.) Both units use common power supply, but should be electrostatically isolated from each other. The speaker must be seperated by several feet, or sonically seperated. The output is controlled by adjusting the 3K pot. When adjusted correctly it will cause ALL (including telephones, hearing aids, tape recorders, bugs, etc.) microphones to squeal at the difference in their frequencies. This will render useless all mics in the vicinity. Aim upward and let sound reflect from ceiling. ><anrek The Conjurer _______________________________________________________________________________
