CB Radio Inline Power Noise Filter Schematic - RC Filter Diagram

This document is a simple hand-drawn electrical schematic (uploaded as "inlinefilter.JPG") showing an in-line power filter for a CB radio installation. On the left is a box labeled "CB" (the CB radio). Its power lead runs to the right through two series resistors and continues to a point labeled "2 Power Supply" (the power source). Two capacitors are shown connected from the power line downward (to ground, implied): one placed between the two resistors and one after the second resistor, forming a classic RC (resistor-capacitor) low-pass noise filter arrangement. The diagram carries no component values, part numbers, wire colors, or vehicle-specific information, only the five text labels: CB, Power, Resistors, 2 Power Supply, and Capacitor. A reader can learn the general topology for building an in-line noise filter to clean up the power feed to a CB radio: series resistors in the supply line with shunt capacitors after each resistor stage. It was uploaded to a 1988 Ford Bronco gallery, but the drawing itself is generic and contains nothing tying it to any particular vehicle, year, or model.
