I thought of filtering out my DC adapter power supply for better radio reception, and I think it worked somewhat better.
Here is how I made my filter:
I took two fat diodes (diode #1N5 something), and connected the anode of one diode to +ve of the battery, and the cathode to the +ve connection point on my circuit board. Then I connected the anode of the other diode to the -ve connection point on my circuit board, and the cathode to the -ve of the battery. I connected the opposite ends of the two diodes together through 1000uF capacitors. It's like almost making a bridge.
I wonder if I should make a bridge.
maybe someone has a better filtering circuit I can make.
