Hi.  I panicked when I heard Int. Xtal was closing.  Since then I heard about  "quartslab" in England and ordered a sideband xtal for  a Galaxy 300---9.1  meg i.f. frequency which makes for an oddball sideband xtal.      Then wanted a schematic for it before they would  make the crystal  and I told them about the BAMA website, where they downloaded the manual.  Three weeks and $31 later I had the xtal and it was RIGHT ON THE NOSE.  Worked great and I would highly recommend them.  We had several emails back and forth and they were really nice to work with.

In viewing Bryan Carling's website the below was posted
for those needing custom crystals. I have no knowledge
of either Brian Carling or Andy Fleischer's skills in producing
crystals so caveat emptor.

OMG NO!  Those are horrible.  They over-grind and use graphite to bring on frequency.  After a couple years, the graphite falls off, and it drifts badly.

Strange - I have been using them for decades and never encountered anything in your statement. I use them for Public Safety, Commercial and Ham projects and they have always stayed on or very close to being on frequency without excessive drift.
PS - Bomar got back in the business to provide crystals and the only they don't so anymore like they used to
is compensate channel elements. Since they are onshore they are my first choice.
