New synth board and birdies

[Carl AB1DD]

Can anyone tell me if the new KSYN3A boards are less prone to birdies than the old ones? I'm having a small problem with birdies in my K3, and have lessened them quite a bit with careful routing of cables, grounds, etc. I do know that they can be nulled out, but I would like to get rid of them more "at the source."

Resistance is futile.
(don't know about reactance, though)

I have a birdie in my K3 at about 21.022 mhz that I believe accompanied my synthesizer upgrade. It's about S1 with no ant and the preamp on - I tried moving the cabling around inside the rig and it had no effect at all.

Apart from that, I just have the "zipper" sound when tuning on certain bands now (on 10 meters on my K3 and my K3S does it on 6 meters), which is known about and normal. Fades almost completely when I have a resonant antenna on 10M

But the birdie is there and audible when I'm /p where 21mhz is very quiet. It's not present in my K3S, so no idea what it is...
