Circuit: Diagram Of Radio Control

0 Comments - in Radio Receivers
Circuit diagram for an AM radio antenna preamplifier that amplifiers the signal before it get to the AM receiver, thus making the AM radio signals stronger for better reception.
This is a RC car project is the transmitter and receiver modules for a Remote Control car, with speed control and continuous steering.
