QRP Z-match Manual Antenna Tuner 3-28 MHz How to use The front panel switch is used to select the mode. When it is in the TUNE position, the standing wave indicator circuit is accessed. When the transmitter is transmitting, the brighter the LED, the higher the standing wave. Two capacitor controls are used to adjust the matching. The rear switch sets the antenna impedance. Note: Standing wave indicator LED. Note: It is essential to check the standing wave before transmitting, otherwise the ORP transmitter without high standing wave protection may burn out. Note: If quick tuning is not possible, use a network analyser for debugging. At this stage the mode switch should be set to WORK. Note: This tuner is for ORP only. Excessive power can cause components to burn out.
