Thanks for doing this work, Ian.
The number of turns on the link coil depends
on the model of BC-459.  Early contracts like
A.R.C. 1470-NY-41 and W.E. 1509-NY-41
had fewer turns than the later W.E. and
Colonial versions.  IIRC, the early 7 MC sets had
either one or two turns, and the later had either
two or three, respectively.  The other ranges
varied in a similar fashion.  My radios aren't
handy at the moment, so I don't remember the
exact number of turns, nor does it seem to be
listed in the manual.  Perhaps you should eyeball it.
