Hi Gary,

Radios are tuned to crystals precisely because inductor/capacitor only
circuits do drift.

If capacitance and inductance were _inherently_ affected by date, time,
altitude, longitude, and latitude, a radio tuned to a station would be
observed to drift as these parameters vary.  In practice it does not. Q.E.D.
