[Elecraft] The case of the reclusive decimal point:

[Catherine Flick & Stewart Fletcher]

K1 Gurus:

I have a K1 that does not display the decimal point.  It has appeared occasionally, but most of the time it is invisible. On one camping trip it was visible for 2 hrs. This weekend it was visible in the late night for 4 hrs , but not visible in the early morning, and it was definitely cold at both times.  At the home shack it is almost never visible.  The only times I have seen it are when I am camping..maybe it is telling me something?  I sometimes am able to see a shadow of its existence if I look at the display at an acute angle.  I have examined the display connections and re-heated the joints adjacent to the point.  I have passed a toothbrush over those same connections and the decimal has re-appeared for a short look around but then returns to its lair.  I assume this is from static electricity.  Could humidity have anything to do with the problem?

Assuming that this decimal can be made to unveil itself long before its brother sun spots make regular appearances, I would like some advise on how to encourage it along.  Otherwise this K1 display seems to be functioning correctly.

Thanks!
