[Elecraft] K3 Main RF Gain problem

[Joe Planisky]

Hi Jim,

Are you by any chance running the RF gain calibration with the Linux  
or Mac version of the K3 Utility?  An earlier release of the Mac  
version and the current release of the Linux version seem to have some  
problems with RF gain calibration.  Everything seems to go right  
during and immediately after the calibration procedure, but once you  
turn the rig off and back on, you get reduced gain and the s-meter  
doesn't go full scale at min RF gain (as Wes described.)  That's not  
exactly the symptom you described, but I don't know what else might be  
messed up in this case.

Anyway, my point is that if you're using a Mac or Linux machine to do  
the RF gain calibration, you might want to try it with a Windows  
machine to see if it fixes your problem.
