Hey Frank! Check this out;
This device looks much simpler to build and use than the field mill. >>

Apparently something had temporarily depressed the propagation of radio waves. At high frequencies, such effects can be caused by atmospheric conditions. But the lower frequencies involved here are hardly affected, particularly not the signals from the nearest stations, which account for most of the power received. It was tempting to think this strange radio depression might somehow have been a precursor to the earthquake.
