A question.. Changing the data mode to AFSK A the bandwidth sets itself up for

BUT when I go back to Data A the bandwith is still set up as for RTTY
But if you leave the setting at its nominal, can you hear the difference as
that bandwidth is selected? I'm not sure I understand the advantage you are
gaining by bringing the crystal filter in later; I'll do if there's
something to be gained, it sounds an interesting approach.

data outputs to activate the proper transverter, you can derive lines to
activate the proper relay at the same time as the transverter.

The new firmware has a compatibility mode added to the KRC2 config menu of
