[Elecraft] K3 Battery Low

[Henry Pollock - K4TMC]

Keith,

That was the problem.  Somehow, I had accidentally bumped the variable
voltage control on the power supply down to 10 volts.

During the contest, I kept wondering why the dial screen was dimmer and
flickered during SSB transmit. I chalked that up to knowing I was using a
marginal AC circuit at a portable site. Sadly, I did not resolve this until
near the end of contest.

73,
Henry - K4TMC
