I wouldn't put too much stock in the S meter readings. In professional radios, this meter is calibrated to strict standards; we're not dealing with that here. The markings are pretty much a nice picture and that's about it.
Use it as a relative strength meter, not an actual voltage level. In fact some old timers would call such meters 'eStimate meters' for exactly that reason

Most S-meters can really be considered a "guesS meter" as they are not strictly calibrated.
For HF, a 50uV signal at the 50 ohm antenna input should translate to a S-meter reading of S9...
good luck with that.
Use it mostly as an indication of relative strength between signals on the band at the same time.
btw... how do you like the S2200x?

S-Meter on this receiver is more for show -- it's slow to respond to tuning/level changes. It looks nice though!

The “S” meter shows you the relative strength of the received signal. It is mostly useful for tuning to the center of the signal. For reception reports however it is not used a lot. Instead the SINPO or SINO codes are used.
S-signal
I-interference
N-noise
P-propagation
O-overall
Usually SWLs leave out propagation, hence the SINO. The values range from 0-5 with 0 being the lowest value and 5 the highest

Sorry for asking and maybe it's just me getting old but this is the first time I hear of this in 50 years of SWLing and quickly googling that brings up zero results -- where is that coming from and why would SWLs leave F or P out? I know that SINFO used to be more common in SWLing than SINPO or RS/RST, but SINO sounds to me like a special code for rating Chinese stations or some of the massive knowledge rot pouring out of reddit?

You are correct. The abbreviated code is SIO. I never use it, so I didn’t quite remember it right. I always use the original code. Info on both can be found here:

Good catch! I must be getting old myself. Memory not as good anymore

...good morning and thanks to all who took the time to respond, I appreciate your input...as I suspected, the meter wasn't very accurate or scientific and I had never seen one like it so I was a bit confused and hence my reason for asking my question...I'll just stick to my tried-and- true SINPO!
Thanks and 73!
