29Mhz-amplifier


Posted on Dec 13, 2012

The only adjustments that require close attention are input, output, and neutralization. The 150-pF capacitor in the input line compensates for impedance mismatch. You tune for maximum signal transfer from exiter to final with an in-line meter or external field strength meter. The final is a conventional pi network. When neutralized, the plate current dip should be at about the same setting of the 20-pF plate capacitor as maximum output.
