[Elecraft] KX3 ERR IOA IOB

[Jim Campbell]

I completed the assembly of my new KX3 yesterday. When turning on the 
KX3 I get an immediate ERR IOA d=001. If I tap the Disp/Menu button it 
changes to ERR IOB d=001. I have checked the cable between the Control 
Panel board and the RF Board several times. A third tap of the Disp/menu 
button takes me to the configuration menu.

I had initially installed the ATU, the filter board and the battery 
charger and as soon as I turned on the power I saw the error messages. I 
had done the configuration to turn on these three accessories. After 
removing the three accessories I removed the configuration for them by 
changing them to "not inst".

I next updated the microcode for the MCU from 1.26 to 1.27. Errors 
remained. Then I did the EEINIT procedure but the errors remained.

The troubleshooting section of the manual shows the ERR IOA and ERR IOB 
entries but does not speak to d=001.

I installed the NiMH batteries after I had completed assembly. I 
attempted to charge them but the charge voltage went from 10.2 V to 11.4 
V over a 16-hour charge cycle. The batteries were obtained from Radio 
Shack and were the Enercell 2500 mAh AA cells.

During the assembly I was VERY careful about ESD. I did the assembly on 
an anti-static mat and always wore the wrist-strap.

Any help would be much appreciated.
