The other thing to watch is the frequency stability. When I used to run digital modes on the KX3, the radio would drift a bit as it heated up. I got one of the XG50 reference oscillators, and went through a temperature compensation profiling procedure, and after that it worked very well. I guess you already know with Elecraft radios that setting the levels works differently to many other commercial radios -- often you'll see procedures where you use the audio input drive to control the transmitted power and saying to avoid ALC, but those procedures and not appropriate for Elecraft -- there you need to set the input level (on KX3 think it was something like 4 bars on the "ALC" meter) then control the output power using the power output knob. Someone else on this list probably has more current information than I which pertains to the KX2.
