Larry,
I doubt that this is a firmware caused problem, but would rather think
it is something that has been gradually failing and got worse about the
time you loaded the new firmware.
ERR PTT normally is indicated when PTT is active during a power on, but
yours seems to be different, and may be related to the KIO3 module - see
the error code "Troubleshooting steps" for that error on page 69 of the
K3 manual.
I would suggest removing the KIO3 and its digital I/O daughter board and
then plugging them back in which will remove oxidation from the contact
pins. See the K3 assembly manual to see how it was assembled - reverse
the assembly steps to remove.
73,
