check out SMTR MD in the manual

> (Advanced) S-meter mode: When set to NOR, preamp/attenuator on/off will
> affect the S-meter. (The default values of SMTR OF and SMTR SC apply to
> NOR.) If set to ABS, the S-meter reading will stay fairly constant with
> different
> preamp/attenuator settings, but SMTR OF and SMTR SC must be re-aligned

also page 51 (owners man D10.pdf) for 'S-Meter and RF GAIN Control'
with help about calibration.
