The 2AT doesn't seem to have a separate PTT line as the TAPR documentation assumes. From reading the 2AT schematic I see that the PTT switch merely interrupts the ground return side of the mike. Has anyone had any experience hooking up a 2AT to a TNC2 (or for that matter to any kind of packet controller)? I'd sure appreciate any advice. 73, Richard N6MPP -------
