Don't forget, an S-meter is a power or wattmeter. It indicates signal
STRENGTH. S9 = 50 pico-watts.

Yeah thats for that tip. But the question is how do you actually build a
piece of electronics that measures signal levels at the receiver
terminals. Or is it reading agc voltage just as accurate. The problem
the method you described is that it will vary from band to band.

I just wonder how field strength meters are designed, especially the new
solid state ones. Spectrum analyzers too have a pretty flat response. I
want to build this ability into my homebrew receiver much the same way
a selective level meter works. Maybe someone has done it.
