(C) LAZY KEEPER'99.
Only for those who have experience in Amateur Radio! "(Who were
not small)
Discussed in this article will focus on the promiscuous and
DEVICE please somnevayuschihsya the legality of the use of this
garbage then do not read.
So, this device is a bug or beetle,
wedged in the gap telephone network (wires to a particular
subscriber), then it automatically feeding from the telephone
network transmits on a frequency you set the conversation the
caller or if the tube is put, he does not respond and does not
deliver on a no signs, and the scutes is difficult to determine
the presence of that very convenient. During the activation it
has a resistance network through the resistor R5, which does
not interfere and does not cause suspicion of a subscriber who
is currently bugged.
Fluctuations in the wire, ie conversation Nemudrenye scheme
in five capacitors, three resistors and transistor modulated
radio wave is caught by any free radio on FM
band reception (from approximately 7 to 100 megahertz?!).
Capacitor C5 is a filter on the noise and stbilitron KS147A
stabilizes voltage applied to the scheme that protects the
circuit from the output failure. Further, the principle is
already clear to you and understand you should not labor.
The only difficulty arises when you set up this
devices that only by an experienced ham who
knows how arranged modulator transmitter is Lameroo do
nothing.
