I didn't say that right. The calibration of the s-meter sets the ZERO point
(well... -73 db point) on the meter. That is the intercept of the equation
for "S" units. You also have to calibrate (eg determine) the SLOPE of the
curve using the attenuator (because we know the attenuator is correct).

S-units (an any input) = S-meter calibration point at fake -73 db +
"Detected signal strength in S units above zero"

So above S=0,

"Where Detected signal strength in S units above s=0" = gain(S=full scale
- S=0) * received signal strength in fake dbs.

You need to set the attenuator at two different points to resolve the slope.

This is very crude so don't kill me... just fix it...
