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.
