It's useful on any rig covering 80, 40 or 20 meters, Dennis. Its 50 uV output is what many manufacturers use as a reference input level for an S-9 signal, although there's no real consistency between various rigs. That 50 uV number came about simply because receiver manufacturers needed *something* to use in their final test and alignment on the assembly line as a "go, no-go" parameter, and 50 uV was chosen many, many years ago for that purpose.
The sensitivity measurements are useful on any rig. The instructions have a few funny comments in them as they try to relate to any rig. For example, there are specific instructions to set the attenuator and preamp, but not all receivers have such settings. Whatever is normally used (if anything) is right. Also on the K2 CW-N is NOT narrow, but simply one sideband. The best way to evaluate the maximum useful sensitivity (or more correctly S/N +N ratio) is at the narrowest selectivity setting. The instructions correctly recommend using 500 Hz bandwidth (if specific bandwidths are available) since that's what the various manufacturers tend to use. Calculating that number in addition to your narrowest selectivity provides something you can compare to many published specs for other equipment. Ron AC7AC -----Original Message----- I am interested in purchasing the XG2 test osc/swr cal. My question...Can the XG2 be utlized on non Elecraft transceivers, or is it only useful on K1, or K2 etc...? I would like to try it out on my Ten-Tec QRP rig and SST.
