[Elecraft] Choking KPA500 and testing a box of unknown chokes

All

I am doing some work on a box of chokes I received and I am trying to
figure out just exactly what mix they are.

Since I run a remote station, I choke everything.  I know the chokes I buy
and what they are, but it is the unknown box that needs testing.

I have a tracking generator, so I am trying to figure out  a test jig.  Do
I just wrap the choke in fleedline, have a common ground and then use the
shield of the feedline to feed my signal over looking for the attenuation
on the receiving end of the generator?

Thoughts?
