Correct!
Thanks for the explanation Martin.
With the TT565 sw version 3.032 a numerical value '0' in the table will
put the meter at position 0
Adjusted it to 209 (which is the value to point at +60 on this TT565)
Just checked S-meter using the Elecraft XG3 Rf signal generator:
-107 dBm shows between S3 and S4 (as expected)
-73 dBm is exact S9
-33 dBm is exact +40
Using a TT565 (bought new in 2004) on fw 1.375b and for 12 months now a
second TT565+RX366 on fw 3.032x7b
Spare 2002 TT565 in the closet.
Now way I am giving up on these wonderfull rigs.

I think the S meter cal function first appeared in a version of the
software before the very last one. At that time I recall it would only
accept 0 for full scale (S9+60) and anything else made it just read 0.
Then I think in just the very last software it got fixed so that
somewhere around 240 is about right.
My guess, it was probably hard coded with 256 which when translating
to 8 bits comes out as all zeros with a carry.
