[Elecraft] Data modes

[Ross]

I have been playing with my new K3 (and enjoying it).
It looks like it will take over from my Orion II as my main tx.

A question.. Changing the data mode to AFSK A the bandwidth sets itself up for RTTY, as it is supposed to,
BUT when I go back to Data A the bandwith is still set up as for RTTY ie very narrow.
I have found the only way to set the bandwidth again to say 2.7khz is to readjust the width using "width and "lo"

Is this normal, or am I expecting too much for the K3 to go back to a normal bandwidth when changing data modes
from AFSK A to data A

Best wishes to all
