IMHO you are correct. As I understand it R and S were intended to report on
how well a signal was being received with T being an honest report of 'tone'
in the case of CW signals. I believe that the matter of signal reports began
to become 'confused' sometime before I first got on the air in 1946 when
somebody had proposed that a 50uV signal at the receiver's input should
result in a S9 reading on the 'S' meter, and that each S unit should
represent a 6db change in signal level from S9 downwards. This 'standard'
had been used certainly in Regions 1 and 2 as far as I know by or before
1946, but most people gave reports based on how well a signal was being
received not by S meter readings (if you had a S meter!!). As an aside I
have the manual for an ancient Eddystone 640 receiver which makes note of
this 'standard'.
Worthy of note is that the input impedance of different types of receiver
having a 'S' meter varied considerably, some as high as 600 ohms for direct
connection to open wire feeders, with the result that the signal power level
required to produce a 'standard' S9 reading was not the same in all cases.
My personal preference is for a real 'S' meter that wiggles calibrated in
dbm at receiver input, but I do not use the 'S' meter when giving reports
unless antenna comparisons are being made for example.
