I haven't specifically used the KXPA100 with K3/K3S, but I've use it with a K2, and it works FB. It should work equally well with a K3/K3S.
One issue is that when you change bands, you need to give the KXPA100 a squirt of RF so it can switch in the appropriate BPF (and recall the appropriate tuning solution if fitted with KXAT100 ATU). You just need to tap the paddle/key. If you tend to use one of those things with a curly cord rather than paddle/key, it may be less convenient.
This is not needed when changing bands on KX3 with KXPA100, or on a K3/K3S with KPA3, because in those cases the amp learns about the band change straight away via the CAT port/auxiliary bus.

Am interested if anyone has used a KXPA100 with a K3/10 or K3S/10.

For those who own a KX3/KXPA100 combination, one home station option (final or upgrade step) would appear to be to buy a 10 Watt K3S and use their KXPA100.

Thoughts?
