it's not just the two quiet fans on the HUGH heat sink assembly,,,,
truly a unique design ....
724 DAYS QUITE COOL very quiet receiver... & love the third preamp
on 6 ...& many step attenuation...
you can VNC the entire set of screens from a computer or tablet.... via
wifi, Ethernet //// VERY REMOTABLE
TO SAY THE AMP IS QUIET IS A LARGE UNDERSTATEMENT... unlike any of
the jet engine equipped LDMOS amps.
As far as a comparison, I was just looking for the beginning of the
thread,,, with the B26 RF kit in the subject line, and any info provided.

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.

## 90 deg C ? wtf?
90 deg C = 194 deg F !
## Are u sure abt this ? That's stupid for a LDMOS device. What is
the ambient temp in the shack when this is going on ?
