Of course I'm sure there are exceptions, but I've not
been aware of traditional "5 kHz deviated" FM usage
on 10M frequencies below 29.0 mHz. It simply a case
of the operator being aware of ... and following ... the
FCC's rules.
I expect/ed to be able to use "conventional" 5 kHz FM
deviation above 29.0 mHz when using my K3.
