Tom, no, I can't tell a carrier from an SSB signal from a birdy.  They do 
have a WaveForm datastream, and maybe you could use that, but I'm certainly 
not that suffisticated yet.

Jim,
congratulations on this work, really "cutting edge" for bats.

Can you tell anything about the mode of signals on the pan adapter? or might
you be able to do so if you scanned it much faster?

Of course frequency gives away probable modes but wonder if you can tell CW
from RTTY or digital modes?

great work!
