Hi All

I have built the circuit on this website

http://braincambre500.freeservers.com/rss(1)(1)(1).htm

and the circuit diagram is he

My question is this:

When I increase the antenna length to say 30cms, from the recommeded
6inchs or 15cms, the circuit does not work. Why is this? I know the
antenna captures RF signals and this current is fed into the circuit,
but I dont know why the circuit stops working - is it something to do
with overloading the circuit ?

Thanks for your time
Shelton.
