1070-1150 Garbage?

["John Andrews" <johna@comrex.com>]

For the last few days, I've been hearing some strange garbage on the AM dial
in the range of 1070-1150 kHz.  I was almost convinced that it was coming
from the 1120 kHz station in Concord (please don't ask me to keep up with
call letters!).  Now, I'm not so sure, as most of the stuff seems to be to
the lower side of 1120.  The other possible candidate would be 1060 kHz from
Ashland, but I don't get close enough to there in my Worcester to Acton
commute.

Can anyone else hear this and provide some clues as to the source?  I'd be
happy to call the station involved, but I'd prefer to call the RIGHT
station!
