WS-19 Crystal Calibrator Dog Bone Question

[Chris Suslowicz]

You would need a suitable length of 3-core braid-screened cable (like the kind that has been cut off) and the correct 3-pin Jones connector to match the plug on the calibrator front panel.

Then it's just a (simple?) matter of making up the new flying lead and fitting it to the existing cable - making sure you get the 12V and 250V connections correct.

Best regards,
Chris.

A further thought: it's possible that you could use modern flat 'earth braid' and slide suitable 3-core cable inside it. The result is likely to look a bit 'too new', though.

On a different note, I suspect the calibrators were only issued to Net control stations (i.e. with actual signals personnel) during WW2, and the lower level users simply netted to 'Control'. Using the calibrator is not that simple, and it's just one more thing to go wrong, so may have been 'dedicated wireless trucks only' issue.

Best regards,
Chris.
