I have been haunting the reflector for a couple of months looking for some
definitive figures on the linearity specs on the KPA-500. The only things I've found have been cert graphs for FCC certification. These are OK but not at the standard of a tube amplifier of equivalent power output. I am surprised that Elecraft hasn't been more forthcoming on these specs. Am I missing something or are these spec not important because most folks are using solid state transceivers that are not necessarily the cleanest exciters to begin with? Incidentally I did order the kit back in April, but am looking for a comfort factor! Thanks for any enlightenment.

Stephen,
I don't have the data that you are requesting, but from your comment about "solid state transceivers are not necessarily the cleanest exciters", I would differ. Solid state transceivers are cleaner than any of the vacuum tube exciters that I am familiar with, and that experience goes back to the mid 1950s. The K3 is exceptionally clean and the ARRL and Sherwood data support that. I expect the KPA500 to be equally clean, although I do not have the data available. Elecraft has been a "good neighbor" for others on the ham bands, and I expect nothing less with the KPA500. 73, Don W3FPR On 6/21/2011 7:19 PM, Stephen Springer wrote: > I have been haunting the reflector for a couple of months looking for some > definitive figures on the linearity specs on the KPA-500.
