[K3] A momentary BAT LOW warning

[Barry]

Was playing around in the contest last night and noticed BAT LOW momentarily
flash across the screen.  I'm using a 70A Astron supply with very little
else on it.  Power connector is tight.  ANy thoughts?

Tnx,
Barry W2UP

Check BAT MIN in the Config menu.
Default is 11 Volts but is adjustable

Yes, BAT MIN is set for 11, and my metered Astron is about 14,

In transmit, the voltage was dropping from 13.3 to about 11 at the radio.
The ground wire side of the power cable had worked loose within its terminal
lug at the power supply, causing excess drop.  Reattached and now the drop
is just a few tenths of a volt.  Problem solved.

Thanks for that information.  This is just one example of those things
that are first blamed on some fault in the rig turns out to be a fault
with something connected to the rig.

That is not limited to Elecraft gear - it can happen with any rig.

Yup. I found a similar problem in my solar charging system.
There was a large loss in the curent/voltage meter. I found it
because the inline auto fuse holders were warm to the touch. It
confused the charge controller leading to slow charging. I'm
still trying to come up with a good fix, but now I just remove
the meter from the system.

I've been having a similar BAT LOW issue only in digital modes when
running more than 80w out. This past weekend I picked up some 45A APP
connectors and 8 ga wire, made a new 5' power cable and all is well. 100
watts with no issue.
