Hi

The “alternatives" also likely don’t have quite the same phase noise / spur performance as the
original part. If you want to run the device as it originally was operated, the crystal is the right
way to do it.

If I understand your question correctly, the interest in FT-243 or other vintage crystal holder formats is just that, they are vintage, historical artifacts, & have some attraction from being so.  They're nice to have to use in vintage transmitters, especially when we are trying to recreate the look & feel of radio stations we either used or lusted for when we were younger & perhaps still Novices.

Yes there are other ways to provide frequency determination & stability but they don't have the same cachet & charm.

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.
