Does the dipper dip on one of these frequencies in te absence of an
antenna?

Is the receiver connected to the antenna, and can you move one of the
dips with the receiver tuning?

Does augmenting the antenna cable move one or both dips?

Does relocating the antenna change the dips?

There seem to be two coupled resonant circuits.
