Hi, I have had a similar problem with my KX3 after installing the "KXBC3 Internal NiMH Charger / Real-Time Clock". I guess I made a mistake when I closed the KX3 cover and I damaged the Flex Cable (E980219). The KX3 is working fine in the most of the time, however, intermittently I get the messages d=001 followed by ERR IOA, ERR IO B and ERR ACT when I turn on the radio. To try to solve this problem I have followed all the advices from the KX3 manual (pages 45 and 46).
After doing the advice of the manual, the radio start working again for hours or days. However, in some case the messages are shown again when I turn on the radio. Here are some details about this symptom and my procedures: If I remove the internal ATU and install it again, when I turn on the radio everything starts working well at first time. So, I can operate with the KX3 all day long. However, if I turn off the radio, wait for few minutes or more and turn it on again, that messages might be displayed. Also, if I disconnect the Flex Cable and connect it again, with or without internal ATU installed, the radio works well at first time. However, If I turn it off for few minutes or more the symptom might goes back. Judging by the Manual it is possible that the problem is related with RF Board or Control Panel. I bought a new cable from Elecraft and now I am waiting for it. I guess it is a good idea before trying other approach. 73. PU2CLR.
