Thanks for the tip but I think the microcontroller is damaged. I guess I will order one. Very erratic. Voltage is ok. When booted it emits a tone constantly when keyed. Rebooting is the only way to stop it. Then it may work. It ?stops responding to the paddle input after a few characters. I am going to look a little more. I think I may have a spare microcontroller. It would be any easy test to swap it.
