Build a Agc System For Ca3028 Rf Amplifier Wiring diagram Schematic
Build a Agc System For Ca3028 Rf Amplifier Circuit Diagram. An MPF102 amplifier feeds IF signals to a 2N4126. A potentiometer in the MPF102 source acts as a gain control. This voltage is rectified by an 1N914 doubling detector, and drives a 741 op amp via a source follower (Q14). S-meter and IF-gain controls are provided.

Electronic Rf Type Battery Charger Wiring diagram Schematic
This is a simple Electronic Rf Type Battery Charger Circuit Diagram. This type of charger couples RF from L2 to an external pickup coil. The pickup coil connects to a rectifier and battery to be charged. This idea is handy because no wire or contacts are required. L2 is 10T #24 wire and L3 is 10T #30 wire. Both coils are mounted on a 1 V ferrite rod.
