After reading all comments, I performed an RF calibration using a -73dBm source and the K3 Utility 1.3.10.15. First run with factory defaults, second run using my signal source. A picture tells more than a lot of numbers: http://home.datacomm.ch/hb9brj/RFgain.jpg
X axis = RF gain position angle in degrees: 0 = 3 o'clock, 90 = 12 o'clock, 180 = 9 o'clock Y_left = CONFIG:SW TEST SCN ADC readout of RF gain pot Y_right = DISP AFV in dBV Contrary to my earlier statement my K3's main RX does show an RF gain non-linearity.
