Software Additions

John Hendricks-2
As I grow older with hearing loss I have become interested in the multitude
of digital modes that are available because they don't rely on good
hearing.  A bandwidth of up to 5 kHz is used by the popular WSJT-X
software.  Could the Elecraft radio software be changed so that K3/KSs
radios (equipped with the proper AM or FM filter) have a "WDATA" mode that
allows receiving and transmitting this 5 kHz bandwidth?  It would also be
nice too do the same thing for the KX3/KX2 but it might not be possible
after looking at the radio design.

The K3 has a 4.25 KHz hardware audio filter following the ADC.  Using
either the AM or FM filter, bandwidth can already be set to 4 KHz
(Shift=2.10, Width=4.00).
