If you waited that long, and paid that much for a radio, (why?) I guess

Thanks

Bill thanks for the link. I see 'Elecraft K4' highly emphasized in
font size, reflects
perhaps your waiting time ? What do you think, does the K4 meet
expectation's ?
The amp probably uses a better quality quiet fans like Noctua etc ?
Does it have PC control to allow remote use ?

been following this thread for a while... still waiting to see a
comparison of KPA VS RF-KIT .
I do know MY RFkit is sitting directly in front of me in my
console...and makes some noise at FT8 800-1000 watts,, some , not
even a lot. On SSB I don't even hear the fans. The Huawai 3KW PS is
96% efficient to start... The pallet has a VERY different heat sink
arrangement.
