KX3 Trans gain calibration issue

VE3WDM
I took my KX3 out on the trail today and for the first time ever I got ERR TXG and D=114? I looked things up on my Iphone and seemed it needed a TX gain calibration. It never has done this in the past but I figured maybe because I loaded on the new firmware that gives me more Transmit power. I took the rig home hooked it up to a dummy load, plugged it into my power supply and ran the TX gain calibration from the KX3 utility. All went well and it passed, I then removed it from the power supply and on battery power I put the rig into transmit (holding the XMIT button in CW mode) and I received the same message. On the home power supply no problem but on the internal batteries I get the error message.

Re: KX3 Trans gain calibration issue

Mike,
I don't have a KX3, but the first thing I would do in this case is
measure the voltage from the batteries when transmitting. Maybe the
voltage is dropping severely enough to cause a problem.
