[Elecraft] K3 S-meter Mode

[Paul Kirley]

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?  

Alternatively, the Owner's Manual S-Meter calibration procedure would need to mention the setting of CONFIG:SMTR MD.
