[Boatanchors] Crystal calibrators for HAM use???

[William L Howard]

Tom B and I have been discussing the Czech R 11 sets and the fact that
many of them are missing the crystal calibrators. I asked:

OK, then, why are there so many sets missing them? Are they useful for

Tom replied:
Hard to say why they are missing. It is a useful crystal oscillator.
The crystal in the low
frequency model is 25 Mhz.  I can't think of a real good use for that.
I noticed on the
Japanese web site that the calibrator he has is missing the crystal.
The post WW2 version of the British WS38 has a calibrator that is bolted
on to the case.  Quite often they are missing.  I think they are missing
because hams think they may be of some use someday.
It would be an interesting question for Boatanchors.


So the question(s) are: What can these oscillators be used for other
than for the RF 11 sets and where are the missing calibrators now. Also
does anybody have an extra one of these?
