When someone defined the generated power as the forward power minus the
reflected power, the entire problem was defined out of existence. :-)

I was thinking about how you changed the impedance of your SWR
meter, and I doubt that simply changing the terminating resistors to
ground on both directional couplers is all you have to do.

I believe this because the SWR/power meter needs to be a Zo ohm
Thru, with a microstrip line of a certain dielectric thickness, and
particular width and spacing from the couplers. And you cannot change
these very easily.

Do you have a schematic for us to see?
