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.
