It is Harry Lythall's bug 5 and I did little modification and this Tx has been produced.
It catches noises of AC transformers (used on any devices) far from almost 10 meter. It's working very nice but if I turned on the TV or PC or Cell phone charger etc then Tx starts to transmit noise. I am using Battery but the noise says "you are using AC to DC adapter" hahaha
OF COURSE I used 1nF and 10uF De-coupler capacitor at supply to filter low and high noises however...
Other simpler Tx is not catching such noise but why only on this Tx? (as C2 I used 220pf and L2 might be higher than 500nH little)
Are there any foolish connection by me?
