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'.
FWIW the external plug-in Eddystone S-meter (Cat.669/E)for the 640 has
printed on the scale "1 DIVISION = 4db", OTOH the internal S-meter on my
680X says "1R = 6db".
