[Elecraft] K3 S-meter Reading with ATT on and PRE off

[Jay Krishna]

I wanted to ask about the K3 S-meter readings I noticed: 1. S7 with ATT off and PRE on2. S5 with ATT off and PRE off3. S3 with ATT on and PRE off These were for a CW signal on 20M; I read that turning the attenuator on and preamp off provides a better signal by lowering the noise level in the IF stages and beyond. I can hear the signal better too, but wanted to ask if the S meter readings are supposed to change with the settings of ATT & PRE? Thanks! Jay (KD6AMA)
