These go from S1 (with just one bar showing) to S9 (9 bars) it then has 12 more bars corresponding to S9 + 5 times the number of extra bars showing. So, if you have an S9+20db signal, there will be a total of 13 bars showing. If you use the K31 setting (set k3 to 1 with the K31; command) the response to the SM command will correspond directly to the number of bars showing, from 0 to 21. Note that the first bar above S9 represents S9 + 5db.

Above S9 the range goes from S9 to S9 + 40 in 4 bars. In the SM command this is changed to go from S9 (at 6 bars) to S9 + 60 (15 bars). The bars above S9 represent 6.66 db, so S9 + 6.66db would be 7 bars, S9 + 20 is 9 bars, and so forth linearly up to S9 + 60 at 15 bars.

OK, thanks to your answer I know now that the SM$ command might report exactly the number of dots that are displayed on the KX2 for the S-Meter. But as I am a white sticker, I cannot read that display and do not know to which S-meter values the dots correspond unless it is written in the programmer?s reference. And there they only tell the values for 6, 9, 12, and 15, but not for the other values.
