the calibration is quite inexact, it's always possible

Here's another fun thing you can do while listening to your GDO on a
receiver.

Tune the receiver carefully when the GDO is at or near the dip. You
will find it is oscillating on two separate (but close) frequencies.
One from it's own tank circuit, one from the tank circuit under test.
Probably the tank circuit under test isn't oscillating in the true sense
of the word, but rather "ringing" due to the power induced into it.

I would not have believed it if I hadn't heard it myself.
