I would first perform the RF Gain calibration using the K3 Utility. The
calibration program measures gain characteristics and applies software correction.
Then run the S-meter calibration.

Looking for suggestions here from someone that might have experienced this
same issue - -
I have (2) K3 units (not the S model) that are acting different when the RF
gain adjustments are turned fully counter clockwise.
Ø Unit one – s/n 1062: When the RF gain is decreased to full counter
clockwise position the S-Meter registers full scale (60db over S9) as
expected.
Ø Unit two – s/n 1193: When the RF gain is decreased to full counter
clockwise position the S-Meter registers only S8.
Facts:
Ø With the exception of the S-Meter readings with RF gain settings, both
units are working fine
Ø Both units have ‘almost’ all mods installed. If not all, they are at
least both the same.
Ø Both units are running the same version of microcode (5.54) (2.88) (2.88)
(1.26)
Ø Both units seem to register very close actual RF gain of stations when
connected when tested on the same antenna
Ø Both units have the new synthesizers.
Ø Both units have second RX
Ø In both cases (both units) I can hear the audio level decreasing linearly
as expected as the RF gain is turned counter clockwise
I have tried to initialize the K3 and reload the firmware resulting in no
change to the RF gain / S-Meter readings.
Elecraft Tech Support suggested:
Ø Calibrating the s-meter – did nothing
Ø Next suggestion – send the rig to California.
Anyone have this issue and fixed it??
