Steve, My K3 has done this several times and each time I had turned the power down while running Ham Radio Delux and then turned off the program. The fix for me is to start HRD again and use the slider to raise the power above 12 watts and all is well again.
I am not sure this is what is happening with your K3, but if you run any kind of computer control program you may want to check this out. 73, Ron, KE6RS K3 #1583 From: Steve Reed <ai...@arrl.net> Subject: [Elecraft] KPA3 misbehaving Today my trusty K3 developed a strange and sudden problem -- I can't turn the power output past 12 watts -- the KPA3 isn't clicking in! It was working perfectly yesterday, but today not so well. Went through all the menus, even tried resetting the radio from scratch and re-enabling the KPA3 in the config menu. The fan test works fine, and the PA test works fine too (I can hear the relay click). But going past 12 watts with the power control no longer works. Anyone seen this before and know what the cause may be?
