Thank you all very much for your responses. I got lots of very interesting
perspectives on my hobby.
I guess I am simply too old-fashioned and don't like pre-assembled SMD
boards. Well, back to the drawing board I go...
Nevertheless, thank you all, I appreciate it.

Out of curiosity, is it only happening with power set to >10 watts?
(If it is happening in QRP mode as well something must be wrong with
your main RF board and its PA, but if it's only happening in QRO mode
it's the KPA100 at fault. I think.)

experience with a powerful AF amplifier long time ago, but there was
another hint - audio was badly distorted.)

Thank you all very much for the answers - I think I understand what I
want from K2 much better now. I hope I'll have as much fun building it
as I had with K1.

have it just for the sake of having a complete rig, but will it have any
benefit or will it be just a potentially useful feature?
