Interesting. I've been trying to copy it, too, but have had no luck 
during the day when it is quiet here. That probably just means that I am 
out of groundwave range, as we've certainly seen that effect on other 
signals. Copying anything weak at night has gotten to be a problem here, 
and I've had no definite results on PBO. I have seen some chirpy traces 
very much like Jay's daytime copy before sunrise, though, so the signal 
is just probably getting clobbered by my local noise.
