Introduction:
A schematic diagram like the one for the 6x2 receiver can seem very intimidating at first. The trick is to break down the circuit into its individual parts, and work on each part separately. Below you can either click on a link in the list or click on an area of the schematic diagram to take you to a page that discusses that individual circuit. By studying each of the circuits individually, you will eventually understand how the entire circuit works. Take your time, and have fun!
