4S-Tuner: What is minimum TX power to drive the SWR and Power LEDs?

Michael Sciascia

In the tune mode, the power to drive the SWR/Power LEDs is provided by the transmitter.   I understand that the tuner is good to 10W, but what is the minimum power that will adequately drive the SWR/Power LEDs?    500mW?  100mW?

I have built several tuners using a led as a indicator. Works ok with my 1/2 watt rigs. 72 George/W2BPI
