    I really haven t tested the PTT input at all yet in the T2. I ll check it out when I get a chance. I m not sure the signals are even properly defined yet.

      If I turn on "Use PTT Input" (using the config utility) the LED

      And when I remove the ground it turns red again. Is that the way it
      should work?
