After installing the KBXC3 charger board I get in A VFO d=002 & B VFO ERR BC3 when trying to enter the time. Firmware is 1.22. Tried re-seating the board and re-installed firmware, but didn't fix the error. The hour digit blinks once and when moving A VFO is when I get the error. Wondering if anyone else is having this problem? Reed W4JZ
