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. 73!
