Well...it'll be a bit of a challenge to use a crystal for the nt-60133
calibrator (FT-243 holders) in the TBX transmitter, which uses (God only
knows why) the large round heavy semi-unique nt-40024A crystal holders.

The CGQ-60133 calibrator is described fully in the TBX-8 manual, of which
there has been a very good pdf copy available for many years at:

This calibrator doesn't seem to be covered in any manuals I have for
earlier versions of the TBX-series.  Perhaps the TBX-8 is the only 
version that used it.
