There has been plenty of discusssion here about power versus db improvement
in signal and I will not address that. I have measured S meter readings with
accurate equipment on probably 25 different transceivers. Surprisingly they
all are quite similar. S meter steps for small signals are around 3db/ S
unit up to a reading of S4 or so. From there until S9 the steps are usually
around 5db/S unit. Above S9 the S meters are usually quite accurate for
large signals.
