- NOTES:
-
- The two top units must be constructed separately. 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.
