[Elecraft] KX3 Power on issue

[lockery via Elecraft]

All,

I just joined the list and have a factory assembled KX3 for about the last 8
months.  KX3 has had little use as I worked on putting together the power
supply and antenna.  I have discovered a new issue and I am not sure what
caused it. 

I updated the firmware to the latest version last week of the release
firmware.

I believe I turned it on after the firmware change, but not sure now.

I updated the heatsink to the one from ProAudioEng.

I added internal batteries 2500mAH to make use of the internal battery
charger and RTC.

Symptoms on power up:

TX light stays solid red.  triangle f (delta f) is solid orange.  OFS and B
square (square around B) are solid green.  The KX3 would not power off, so I
removed one of the internal batteries which allowed the unit to power down.

Thought issue was releated to internal batteries not being powered from a
higher current source, so I put battery in and added external power.  Same
as before and had to remove battery to power off.

Went to just external power, issue remained but I was able to power off. 
Sometimes the KX3 power ups if I hold the buttons to turn it long enough.

Only change I did on the firmware beyond updating it was to have a startup
message with my call.

I would appreciate any thoughts on where to start trying to figure out the
issue.

Thanks,
Stan Frady, N1BBS
