Don, W3FPR used to do much of this work on K2 transceivers, but he has
retired from that role. Dave, W8FGU has assumed Don's role. Alan, W3DVX
also provides such services. Both have posted periodically to this forum.
There may be others who are experienced K2 upgraders, but these are the
folks that come to mind.
I built my KPA100 15 years ago or so and only recently I investigated
updates. The KPA module has seen a number of design updates over the
years and it makes sense to investigate. I've updated mine (thanks
QRP-shop for getting the mod kits in Europe, through Corona times!) and
at the end of a long evening I have a bag of swapped-out parts and a PA
that worked quite a bit better, feels like a new unit.
I have not used one of the upgraders (being in Europe, postage and
customs would probably have me mortgage the house, frankly) but I do
recommend updating. It is too bad you don't have the setup to do it
yourself because on K2, these mods really are simple and can be done on
the kitchen table.
