An exception would be radios that have a signal strength meter in dBm,
which is an absolute scale.

Millivolts?

actually the palstar and the drake scales are in Decibels, while the
kenwoods scale is in Db at the top and millivolts at the bottom. also
before anyone asks my rf gain is fully clockwise on both the drake and
kenwood. the palstar doesn't have a rf gain control.

The RF gain control just sets maximum sensitivity of the radio and does
not change the gain of the radio so by turning all the way down you are
at the radios published maximum sensitivity. As you turn it up you are
desensitizing the radio. If you turn the control so it rests at S3 then
you would only be able to hear signals greater then S3. The AGC would
work on signals higher then than S3. The radio will behave exactly the
same for any signal greater than S3.
