To be fair, we have had one instance of the problem, and that
station was running the battery critically low. In fact the
battery failed at that voltage (something like 10 volts) and
had to be permanently removed from service. Perhaps the answer
is to take the battery manufacturer’s advice and not to run
the batteries below 11.5 volts. I believe the K3 has a
low-voltage alarm that can be applied to the problem so that it
gives a warning at the critical voltage and won’t continue
until the power is corrected.
Thanks for reminding me of the details. The 100W CQP incidents
and the 5W FD ones get blurred in my mind.
Yes, the K3 has a low voltage warning. The level is controlled
by the "BAT MIN" CONFIG menu setting with a default of 11V. It
sends out a beep tone and flashes BAT LOW on the display. If you
use a boost regulator like the TG Electronics Boost Regulator,
note that these may introduce a junction voltage drop which will
cause the warning to sound at a higher voltage.
