[Elecraft] KX3 ERR IOA IOB

[Matthew Zilmer]

The 10.2 to 11.4V is about right.  I'd suggest you contact support for the IO errors.

Subject: [Elecraft] KX3 ERR IOA IOB

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.
