What happens if you remove the wire from the T/R pin?
Are you sure the PTT button is not stuck pressed or something like that?
There are two things that can switch the minima in transmit: the ptt button
being pulled to ground (pin 5 of the arduino) or the cw key being pressed
(pin 24 of the arduino).
In normal rx configuration, both should be at +5V thanks to the internal
pull-ups resistors.
