This move will also be of great interest to cave radio users, although I=
 have not yet looked at the map to estimate the effect on cave-to-surface=
 communications.  

Anyway, there is no substitute for experiment. May I ask people to measure=
 the Loran level on 87kHz USB before, during and after the move? As well as=
 doing it with your normal home antenna, it would be helpful if you could=
 try an earthed dipole (10 to 50 metres long with the ends earthed by=
 skewers or tent pegs.  The receiver should for preference have a high=
 input impedance).

If you could do some measurements in caving areas that would be even=
 better!
