I can't speak for the K3 designer(s), but not all modes elevate or produce IM at the upper end of the output power curve. CW is one such mode, although other non-IM artifacts may be possible above 100W. There are times when driving a low-gain, GG amplifier (e.g., 3CX1200 w/ untuned input) when the operator wants to drive it to its maximum capability but in order to do so, something a bit more than 100W is required. It's not worth getting into a discussion as to whether the added power increase from the extra drive is worth it -- but some ops want to utilize their amps to the fullest capability when conditions permit. But that same op needs to understand that in IMD-generating modes like SSB, the K3's power needs to be throttled back to specified limits. When running an amp, s/he may safely achieve 1500W in CW, but must then settle for something less (e.g., 1300W) in SSB mode.
