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.
