Michael's comments re the use of 4.43 XTALS are worth noting Jon.
I think they are about £1 each and £10 worth will provide enough for some
experimentation, if nothing else.
Filters are often grossly misunderstood and there is nothing like some
real
'bench time' to turn theory into real understanding.
Seriously, you may find the tinkering/ experimenting bug bites. Even if
you don't go on to build things like radios, it will help you understand
operating and repairing them.

A positive contribution to the discussion.

Well done, keep it up!
