John,

In the last situation, it took me several weeks of recording
the passes before I finally got a callsign.  I can start recording
again.  I'll try to own this problem, assuming it's happening
again.  If anyone gets a good recording of a callsign, could
they please email it on to me, along with date and time?  I'll 
contact the responsible operator and then forward to Riley 
if it seems necessary.  If it's the "Mexican Taxis" there's not
a lot we can do.
