  13. What it is
  14. ----------
  15.  
  16. This handy little device can be used for two purposes. The first is a FM bug,
  17. which transmits on the FM frequency, thus making it extremely easy to pick up.
  18. The second is a FM station blocker (which can be really fun if you are pissed
  19. at someone who just happens to be listening to the radio. In this case, you 
  20. can do 1 (or both) of these: A) announce through the bug (on their station)
  21. that Fred (whoever is listening) has just won 1 years supply of orthopedic
  22. shoe pads, or B) disconnect the mike, and let it fry the station.) In this
  23. file, I will make some incredibly lame schematics, which any fool can follow,
  24. (lets see you make good schematics with Apple Writer), and tell you all the
  25. junk you need (duh..) Ok, if you have no electronics background at all, go
  26. ahead and try it anyways (hell, it's not my money your wasting on parts)

  72. How to operate
  73. --------------
  74.  
  75. 1. Turn on (duh..)
  76.  
  77. 2. Turn the variable capacitor until you are on the station that you want to 
  78.  use (preferably towards either end, so if they turn on their radio, they
  79. don't get a bunch of audio feedback when they hit your station)
  80.  
  81. 3. This bug does not have a long range (50 ft max), but if you use a large 
  82.  antenna on your stereo (like the rooftop kind) the range is greatly increased
  83. . I prefer to use a AM/FM walkman, so I can get close to the bug, and tape what
  84. I want.
