Hi,everyone. Actually I'm a college student now. I'm so interested in electronic,and I always did some design and research.

Recently I've made two different circuits to receive RF using LM386 but they doesn't work. I've changed the values of C2 and L1 to change the frequency. I've also changed the gain but nothing happens, more detail of my IC could be found here: http://www.kynix.com/Detail/274538/LM386.html.

The problem is that I hear a sound of noise or buzz from the speaker. When I touch Pin 3 (The input) or the Antenna, The sound become higher but anyway no radio station is received.


I've made a radio transmitter using a transistor before so, I turned it on. The receiver circuit received the song Which is the input of the transmitter. It receives no matter the values of the C2 and L1 of the Tank circuit so, I removed the tank circuit and connected the antenna directly to pin 3 and It also works receive the song.

Why it doesn't receive any radio station although it receive the signals that are transmitted by the transmitter circuit that I've made?

What can I do to receive radio stations? ( I live in area Where I can receive good radio stations AM and FM from my cell phone and Radio device )
