- You can use a Q meter to measure the Co of an inductor so I suppose
- you can do the same for a transformer. You look at the capacitance
- needed to achieve resonance at two frequencies then use some maths
- to figure out the extra C. You can also measure leakage inductance
- and parralel inducatance of a transformer.

- H.P. sell one that goes to 70 MHz or so. They can be had for about $4K
- on the commercial surplus market. The Marconi TF1275 is better but
- is older and may be more difficult to find.
