Hello guys,
I decided to design an AM radio with an Op-amp; it works with a 9V battery.
Ok here it is, Please put your comments if you think I can improve this circuit (I am learning Op-Amps yet).
I have a question too, I have used a coil and a variable capacitor out of a one channel Am radio for this circuit, But it just receives our local station (the signal becomes weaker when I turn the variable capacitor but I am not able to get another stations). What's the reason?
Does it comeback to the nature of my design or…??
Thanks.
P.s. does everybody know how many volts (I do not know if I am allowed to ask how many currents though) I should expect out of the coil part?
