[Elecraft] (K3) Saving and Recalling M1-M4 per-band quick memories

[Wayne Burdick]

Hi Doug,

Filter bandwidth is stored per-mode. At present, all data sub-modes  
share the same bandwidth. I'll look at what would be required to split  
them out.

Meanwhile, you could use the user-programmable NORM settings, 1 and 2,  
to switch between two often-used bandwidths in DATA modes. See page 24  
of the owner's manual.
