Many thanks for the update. A third possibility (albeit perhaps more remote?) -
the signal is PI/4 DQPSK... The Gardner/Costas code needed patching to

In any case I've got no particular attachment to the Gardner and would actually
be very happy to see something that dusts it (and to offer any help in that
effort)...
