[ARC5] A crystal or a stable signal source?

[Leslie Smith]

On a parallel 'track' to recent postings about FT243 crystals I ask:
is the shape/pinning/authenticity the focus of interest OR the merely the
ability to generate a stable, known (and even synthesized/variable)
frequency?  What if the 'crystal' was in a box, say 2x2x1 inches?

Yes, this forum has a specific focus - ARC-5 sets, but many here are 'ham'
operators.  So I'm asking the question to a wider audience than those with
ARC-5 interest.
