I was able to pick it up here in NJ last night-- it wasn't very loud, 
but I was able to record it. There seemed to be another signal that 
would sometimes come in over the top of it; a loud, humming carrier type 
of sound that would begin and end noisily, as if there were two wires 
accidentally making contact and letting a signal through. Maybe that was 
local interference-- in any case, I can't hear anything on that 
frequency right now...

The digital signal reminded me of something I'd heard near 150 kHz on 
LW, although that one isn't coming in now either...
