My guess is that there's an external amplifier on the 200mW card and there isn't on the netgear card. This "distorts" the power levels and thus the measurement of the signal/silence levels. : Alternately, any suggestions on a good way to normalize the data I'm : getting so that either card would be useful? Good luck. I've tried to come up with a good formula for this that works for my 10 cards and have failed. Warner
