This includes the K3; manual RF gain control or AGC are not applied to
any stage ahead of the first mixer.
The "RF Gain" control operates on only one stage, the 8.215MHz IF
amplifier, which is also controlled by the hardware AGC.
The only controls in the K3 that affect signal levels *ahead* of the
first mixer are the PREamp and ATTenuator buttons - just two steps of
about 10dB each.
