I heard a local New England signal today that sounded like auroral 
scatter but just worked him and didn't play with the Hi-Z RX antenna 
& just left it in one place depending on time & DX. Might have been 
the same person, I don't remember his call. I was S&P until this 
morning so I was listening for the faint sigs as much as anything.

Now to get my logging program to produce a proper cabrillo...
