This is a RF power amplifier that works with any radio, mobile, fixed or handheld. The power gain is 8 to 10 times, 10 watts output for every 1 watts input, 20 watts output for every 2 watts input, 30 watts output for every 3 watts input.
This manual provides step-by-step assembly instructions for the Ramsey Electronics PA-1 RF power amplifier kit, designed for 2-meter amateur radio use. It includes parts lists, schematic diagrams, and tips for soldering and mounting components. The kit delivers 8–10x power gain, with maximum output of 35–40 watts and max drive of 8 watts. Users must mount the RF power transistor to a heatsink before soldering. The manual also covers troubleshooting, installation, and customization options for enhancing performance.
