And on second thought, since Matt was hearing static crashes with delay 
between his two receivers - one imaginative explanation could be that 
they are statics originating as lightning from the Southern hemisphere 
travelling both in the ionosphere (direct) and on a magnetic field line 
(delayed). Each of his two antennas could have mainly picked up just one 
of them.  Such static crashes are responsible for whistlers at much 
lower frequencies (kHz - audible frequencies).

The delay difference would be half of the range I indicated for magnetic 
field line propagation, i.e. 70 ms and up, depending on the location.

Well, I don't know how credible or frequent this could be, but I think 
there is a remote possibility for such phenomena.
