[Boatanchors] Measuring Swinging Choke values

[Mark K3MSB]

I'm trying to measure the inductance of a swinging choke that's come into my
possession.

I don't have a DVM that will measure into the Henry range,  so I use my
restored IT-28 with an external Inductance standard to measure large chokes.

Using several different known inductors as standards,  my IT-28 gives me
correct readings for other known inductors.

However,  for any swinging choke I try to test,  the IT-28 gives me no
reading at all.

What am I doing wrong here?
