Caught tail end of message of unid transmission. Very good reception.
1805 "I said four overbid, repeat, I said four overbid." Then, series of phonetically pronounced letters (IE: Yankee, tango, etc) then "This is Bookcase out" Then off
1817 "Standby message follows." Letters follow..... "I say again, four overbid, four overbid." then more letters. This is Bookcase out."
