Hook up amp to radio



Simply put this circuit doesn't take much to make. It surprised and annoyed me because it gave me a radio signal when I was trying to make a backpack boombox circuit, so I fiddled with this and I present it to you here. And here are the 4 steps to creating this circuit.
(Please realize that when I talk about the pins I refer to the pins in counter-clockwise order from the clocking mark (probably an indent or circular mark at one end of the chip near pin 1. Pin 1 is the most counter-clockwise going down the left side to pin 4 and continuing at the bottom of the other side at pin 5 going up the right side to pin 8.)

1. Plug in your op amp and add a jumper wire from pin 6 to power and a jumper from pin 4 to ground.

2. Plug another jumper wire from pin 2 to ground and plug your antenna into pin 3.

3. Plug your 100 microfarad capacitor's positive side into ping 7 and the negative side into ground. Plug one your 1000 microfarad capacitor's positive side into pin 1 and the negative side into pin 8. The other 1000 microfarad capacitor's positive side into pin 5 and the negative side into a blank space on your board. Plug your speaker's positive side to the last capacitor's negative side and the negative side of your speaker to ground.

4. Plug in your battery's terminals to their respective rails (red to power, black to ground)
 and then (if you have a switch added) turn it on and simply move your antenna wire around to get your signals. If you want a good signal using a metal fan cage works very well.
