Everyone except the receiver (and transceiver) manufacturers. If you
run a curve of S-meter reading vs input voltage using a calibrated
generator, you will find that it's close to 6dB/S-unit around S9, but
close to 3 dB/S-unit when you get below S6 or S7. And I'm not talking
about "junk" receivers -- I've done this with some very good radios,
like TS850's and FT1000MP's. No, I haven't done it with my K2's.
Someday.
