[Elecraft] P3 Issue

[Ken Widelitz]

About 8 hours into CQWW CW, one of my P3's bandscope function stopped
working. I checked the cables. I powered the unit off. When it came on, it
worked for a few seconds. The outboard monitor worked for a few seconds.
Then it stopped working. I did this a few times with the exact same
results. I never turned it or the radio off after the contest. This
morning  before swapping P3s to make sure it was a P3 issue, I turned the
P3 off and when I turned it back on after just a few seconds, it worked
perfectly. I felt half blind during most of the contest, so I want to make
sure I don't run into this again. Any suggestions.
