If you waited that long, and paid that much for a radio, (why?) I guess your entitled to highly emphasize *K4.*
LOL

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.
