You then raise the sensitivity by sweeping towards 0.2v, letting the radio's voltage flow by the potentiometer (gate) because it can now block less voltage that the radio is putting out.So the amplifier stage will work the same from different signal input voltages. As long as the output power rating set by the manufacturer is not surpassed, the amp will work fine without overheating.BTW, nice setup. It looks imposing.</blockquote>
