Hello all..

Bill,

Forgive my intrusion, but are there any resources out there that can
generate a trunk.tsv file, given RadioReference.com data as input? I can
hand craft them, but I travel a fair amount and it would make things
easier in new places. If there is not a script for this out there, I'd
be happy to throw one together.

Thanks for your time.
