Re: SWR BRIDGE hows it work????
Is this one of those that requires you to set it & then check SWR ?
If so place the switch onto set or forward or what ever the thing says, rotate knob until needle is on set on the dial & then flick the switch to reflected power, or what ever the thing says.
Give me a cross needle meter anyday.

It should have a calibration impedance you set it to to give FSD then unplug and use it without adjusting anything. If you havent got one you can use a 1/4 of coax but its freq relative so will only calibrate at one freq. have you tried a 50 ohm dummy load?
