(Pt-15) ZX-SSB-II Front Panel Development (Part 15) - RF Power Detector module

This video explores the ZX-Front-Panel's Tune screen which presents the Forward and Reflected RF Power bar meters. When the Tune screen is selected, a digital output pin on the Arduino controller causes a relay on the balanced modulator to unbalance the diode bridge, which causes the carrier to be output through the final RF power amplifier allowing an antenna coupler to be tuned for least reflected power.
