[Elecraft] KX3 Question on S-Meter Calibration

[Walter Underwood]

I’m pretty sure the K3 has an S-meter absolute mode that adjusts the S-meter reading when preamps and/or attenuators are turned on.

The KX3 is supposed to have that mode, but it is not implemented. From the manual errata:

"Not implemented: S-meter absolute mode (MENU:SMTR MD); addressing of multiple transverters (XVn ADR)."
