This is new to me:-)

I think it depends on the transformer. It should be easy to make the
transformer work from 1.8 to 30 MHz but maybe the frequency divider
will have difficulties to divide 120MHz by two. I do not quite remember
how high the 74HC74 works.

Yes, it seems so to me.

The bandwidth is already adapted to a Delta44 as far as I understand:-)
