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

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