At the risk of beating the same old expired equine, this is because the
radio's SPLIT function is disabled unless you already have the other VFO
and mode set in a way that allows you to go SPLIT. This is a bad thing and
a flaw in the K3's operational logic.
I have pointed out that this is a flaw previously, and yours is just
another example that proves the point.
The way it should work is that when you PRESS and HOLD SPLIT,
***AND *ONLY IF* both VFO's are NOT on the same band and mode***
the radio should do a VFOA->VFOB and then enable SPLIT. Otherwise, if both
VFOs are already on the same band and mode, it should only enable SPLIT
without first making the VFOs equal.
The error message that it won't allow SPLIT when the VFO and mode is
different serves no useful purpose and is a waste of time. Talk about
ergonomic overhead!
