I had looked for SX-117 pictures on the web, but I could not find a picture
clear enough to determine whether the meter is at full scale or quite full
scale when receiver is off. The picture on the instruction manual is not
clear enough either. I was looking for someone who owns an SX-117 and can
look at the meter.

Sticky meters can sometimes be fixed by finding the mechanical zero
adjuster and working it back and forth several times.

The SX-117 meter has no adjustment

But I have finally determined that the plastic lid has static charges and
the meter indication strongly varies with lid distance. So I washed the lid
with water and the static charges have totally disappeared. The meter is not
at 9+60 steady. Still, as the scale end is actually 9+70, I would still like
to hear from an SX-117 owner whether the meter is a 9+60 or 9+70 when
receiver is off.
