Re: [IRCA] kdka / radio reloj

[Scott Fybush <scott@xxxxxxxxxx>]

The answer, in this case, is probably the extremely auroral conditions 
that many DXers have been reporting the last few nights. That can create 
considerable enhancement to the south while completely wiping out 
anything coming in from the north.

And KDKA's groundwave is notoriously bad, so to have it disappear at 50 
miles isn't terribly surprising at all.
