I haven't read all the details but I have the impression that you need to be able to set 1 and 50 microvolts which requires rather considerable attenuation for some common signal generators such as my Elenco SG 9500. Is my impression correct?
On the Clifton Laboratories web site, there is a graph labeled Elecraft K3 Transceiver Incremental Incremental RF Gain Reduction 9dB) versus RF Gain Value. Is this effect along with basic calibration that the gain calibration is intended to correct? My K3 doesn't have the discontinuity or discontinuities that others have mentioned; I just curious.
