I find that most of them seem to sort of follow the rule that 4uV is S9, 3dB
down is each S-Point, that's for VHF/UHF.

The rule voor 50µV = S9 does still exists, this is voor HF, @50 Ohm input
impedance at receiver.
"They" (radioamateurs) use another rule for VHF.
It's in the software MultiCalc, Google will find the adres, it's for free.
Official or not, if everyone use this rule then it is a standard for me.

Is there a standard RF input level per "S" Unit?

If so, please post the location. Thanks.
