The original question was to use the 500 Hz and 250Hz filters
(e.g., 2.0, 500 Hz, 250 Hz) in digital (RTTY/PKT) modes in 
addition to CW.  Your solution does not address that problem.

The problem with the Mark-V and Field is that bandwidth selections 
are limited as follows: 

Mode          Nor        Nar1       Nar2    

AM          6.0 KHz    2.4 KHz    2.0 KHz
USB         6.0 KHz    2.4 KHz    2.0 KHz
LSB         6.0 KHz    2.4 KHz    2.0 KHz 

FM          8.0 KHz     n/a        n/a 

CW          2.0 KHz    500 Hz     250 Hz
CW/R        2.0 KHz    500 Hz     250 Hz

RTTY        2.4 KHz    2.0 KHz    500 Hz (or 250 Hz - menu 5-4)
RTTY/R      2.4 KHz    2.0 KHz    500 Hz (or 250 Hz - menu 5-4)
PKT         2.4 KHz    2.0 KHz    500 Hz (or 250 Hz - menu 5-4)
PKT/FM      8.0 KHz     n/a         n/a
