[Elecraft] Field Day experience with K3

[Peter Wollan]

The problem here isn't the battery AH capacity, but the voltage
supply.  It could be dropping below 10 vdc because both radios are on
the same supply, or because the power supply wires are too fine gauge,
or because the battery is defective.

The K3 is less robust to supply voltage than the other Elecraft
radios.  The K2 is rated for 10-15 volts;  the K1, KX1, and KX3 go
down a lot lower, I think 8 volts.  I looked at the K3 documents to
see what minimum voltage it requires, and I couldn't find it -- I
think it's something like 11, but it may be 11.5 or even 12.

You'd probably do fine just by using a separate battery for each
radio, and not letting it run down too far.  A voltage booster isn't
needed, as lots of operators all over the world have demonstrated.
