You can't do anything except 0-15 after the dash on RF. It's a limitation of the AX.25 protocol, not of the T2-135 specifically. There are exactly 4 bits available there in the packet header, which can be used to represent 16 numbers from 0 to 15. -- Curt, WE7U. archer at eskimo dot com http://www.eskimo.com/~archer Lotto: A tax on people who are bad at math. - unknown Windows: Microsoft's tax on computer illiterates. - WE7U.
