1-25 on the bottom and 12-4 on the control connector are the
same thing.

Remove the 1-25 jumper.
Are you using a control head?
Unhook the IRLP board completely.
Let both pin 13 and 16 float in the breeze separately.
Completely unconnected.
As I said earlier, pin 13 is PTT and pin 16 switches the
receiver between carrier and PL mode. It has nothing to
do with the transmitter. The two should never be tied
together (unless both happen to be grounded at the
same time).
Power up everything and the radio should be in receive.
If not, find that problem.
Ground only pin 13. It should go into transmit. Ungrounded, it
should go to receive.
If not, then there is another problem.
Once you have it that far, then write back.
If you feel this is more appropriate to handle off list, that's fine.
