Ken, I usully use the XG1 and check the S-meter with the preamp off on 40 meters - if the AGC Threshold is set for optimum receiver performance, and CAL S Hi and Lo are set the S-meter usually comes right in at S-9 with the preamp off.
Yes, the manual is non-committal on this point, so I take that as an indication that either way may be right, the S-meter is not an absolute device, the point for S-9 varies all over the place from one receiver manufacturer to another anyway, so other than being useful as a relative measurement, I personally don't worry about the absolute calibration, but I set it as close as possible for other's K2s that I work on. In other words, do what suits you best. 73, Don W3FPR > -----Original Message----- > > I found the XG2 manual and the K2 manual a bit ambiguous on the > issue of weather to do CAL S-Lo and S-Hi with the preamp on > or off. > > I guess that it's a bit of YMMV but I've found if I set the S meter > with the preamp on, then I get no background signal above 20m. > > OTOH, If I do it with the preamp off, then the S meter seems too > "hot" below 30m.
