When operating in JT9+JT65 mode, changing band to 60 m has moved the

"JT65 nnnn JT9" blue line to 0 Hz.  Now it also moves the spinner to
0 Hz, as it should have done.  Subsequent QSY to another band will reset
the blue line and spinner to where they had been, before the QSY to 60 m.
Thanks to W9MDB for this patch.
