bc107 simple receiver
hello friends,
i just wanted to get your advice before i can try this out.
i intend to build a simple am receiver in a "BREAD BOARD".
my idea is to first have an
1)antenna(about 1m)
2)tuned circuit(L || C(var)).
3)this output is given to a double stage (bc 107 bjts), with gain=100*100=10000 so that it is amplified well.
4)this amplified output is then given to an envelope detector.(using a germanium diode and R and C combination).
5)this output is then sent to another single stage amplifier.
6)the output is taken from speakers.
my doubt is,whether my logic is correct? is there any practical problem in the above steps? or any other alternative?
thanking you in advance,
amrith.s
