When I tried setting K3 CONFIG:SMTR MD to ABS, I found that the S-meter reading
then stayed constant regardless of the setting of the preamp/attenuator, in
agreement with the Owner's Manual addendum.
However, the reading for a 50-microvolt input signal (with the preamp on and
attenuator off) falls from S-9 to S-6 as CONFIG:SMTR MD is changed from NOR to
ABS.
Shouldn't a 50-microvolt input signal produce an S-9 reading regardless of the setting of CONFIG:SMTR MD?
No, that is what the ABS mode is available. You are seeing the correct
response.
In NOR the S Meter is affected by PRE and ATTN.
The default calibration assumes: NOR, PRE ON and ATTN OFF. The drop you
are seeing when you go to ABS is because the PRE gain is no longer
allowed to affect the S Meter reading.
