may I respectfully ask to add one or more digital rows customizable by the user in addition to the existing one that you are currently modifying to "replace PSK with any digital mode"?
+ Providing the ability to enable users to select multiple digital mode families for realtime DXCC award tracking would require considerably more effort, as there would have to be significant changes to user interfaces in DXKeeper and DXView. This "first step" provides the option to replace PSK with one of these digital mode families: CHIP,
DOMINO, FT4, FT8, HELL, JT4, JT65, JT9, MFSK. ISCAT, OLIVIA, PAC, QRA64, or THRB.
Whether and when there will be follow-on steps, e.g. adding more user-specified digital mode families, will depend on interest level from the user community and competition from other development tasks that would deliver more user value.
Being a RTTY enthusiast, my actual needs would be perfectly satisfied by the actual existing row that is going to be modified, but maybe other users could be interested to follow their progresses in more than one digital mode.
+ This "first step" won't enable you to replace PSK with RTTY, as doing so would requires broader changes to the realtime DXCC award tracking mechanism arising from the fact that there's already a RTTY row in the DXCC progress table; this row was originally provided to track RTTY progress exclusively, but years ago was expanded to track what the ARRL now calls the DXCC Digi category.
