[Elecraft] Power issue

[Matthew Zilmer]

Check the terminal voltage when the batteries start charging.  If it's below 13.8V when loaded and charging is enabled, you would get the LO SPPLY message.

The KXBC3 charges at a VERY low rate (around 200 mA), so it's not likely that the charging itself is loading the PS down.

Hello folks,
Just got my new KX3 and couldn't be more excited but I'm having a problem I hope the group can help me solve. My KX3 is factory built with the KXBC3. I installed new Powerex 2700mAh NiMH batteries and went to charge them. I had the KX3 connected to an Astron SS-30 and got a "LO SPPLY" message. I thought maybe due to the set screw type connector the Astron has, it wasn't getting a good connection. I was wanting a new power supply anyway so I went to Radio Shack and bought a new 13.8VDC 3amp. I just hooked up the KX3 and still get the same message. The NiHM batteries are now low enough that the rig won't stay on.
Am I missing something?
I posted this to the Yahoo group as well.
Thank you
Bob
