Hi [USER=1260]@Dr_DX[/USER]
Please see the attached S meter values.
This is data from 3 radios, an early Nii, an Nii from around 12 months ago, and a CRT SS7900V.
Note - I adjusted the SS7900V S meter readings for exactly S5 (-97dBm) / S7 (–85dBm) / S9 (-73dBm). Not because of any S meter problem, but because I wanted a semi-accurate -73dBm S9 as the SS7900V is used as a monitor radio on my bench.
None of these radio's have had any issue with noisy RX or increased S meter readings, They all work correctly. They will all rest at S1 or lower on external antennas on a quiet band.
The CH-52 RFG = 00086 setting has not been touched on any of these radios. They are all the default value.
Also, regarding your other question about the "RSS12" settings - I would simply "adjust this to taste", and only if you need to. Mine track well enough at levels over S9 (-73dBm) as they came, so I did not look at what S meter point this "S12" will set. A general indication over S9 is all that is really needed for 99.9% of users. It works fine here at the defaults.
FWIW: Most (but not all) of the issues reported on this topic appear to be based on what the user "sees" on the meter, and not what they actually "hear" from the speaker. I have hoped to see a "noisy" radio on my bench to confirm if this is environmental, hardware, or a perhaps just an S meter calibration issue, but as yet all of the radios I have seen have worked correctly.
