I just had an email from a feller that used my Oshkosh frequency list and he

133.85 and 126.6 both seem to be used by the Warbirds Airboss. Those
will let you know when explosions are coming.
If anybody has any more updates, I'm ready to take them and refresh the
list.

I listened to Airboss on 133.85 most days.
It stands to reason that 126.60 was used as it was the tower freq for 18/36.
