Can someone please tell me what does the S-meter display when the receiver
is turned off?

Mine is on the 40 mark, that is not full scale (which is 60).

Tony, when the receiver is turned off, there is no power to any circuit
and the S-meter should be at zero. If its up scale, its probably sticking.

You will find a handbook at:
http://www.rigpix.com/hallicrafter/sx117.htm
There may also be one on the BAMA site.
The S meter appears to measure the cathode current of a
controlled IF stage so its a "backward" meter which should
measure maximum up-scale with the power off.
Sticky meters can sometimes be fixed by finding the
mechanical zero adjuster and working it back and forth
several times. If this does not unstick the meter one must
get into it and clean the mechanism. The stickyness may be
just dirt in the meter bearings but can also be caused by
metallic particals caught in the air gap of the magnet.
Meters are quite delicate so if you decide to open it up be
very careful. With any luck the zero adjuster trick will fix
it.

Hi Jeep,

glad to read from you again.

The Hallicrafters SX-117 meter must at be at full scale when the receiver is
off. When it warms up the meter goes to zero, and then it works normally. It
is the same on my SX-146.

The only thing I was worried abuot is that the meter is not quite at full
scale (9+40 instead of 9+60) and there is no adjustment. But now I have
realuzed it is only a matter of static charges, as removing the plastic lid
the meter goes to 9+60. And when the lid is not yet in place the meter
reading varies a lot with lid distance, this clearly signifying static
charges. I washed the lid with water and now all is OK.

Did you already change your QTH^?

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.

The illustration on the web site above clearly shows the
meter at full scale. Perhaps the cover should be treated
with some sort of anti-static cleaner.
Not all meters have external mechanical zero adjustments
but most have some sort of internal adjustment. Does it go
to full scale with the cover off?

Yes it now goes to full scale with and without the lid. So the problem
caused by the static charge is solved. But still I cannot determine from the
available pictures whether the needle should be on the last number (+60) or
at the very end of the scale (corresponding to +70). Need somebody to look
at.

I have two SX117's
When off, the meter pointer goes right through the center of the 0 in '60'

I guess a definition of "full scale" would have been appropriate...hi!
These meters are designed to operate backwards so "full scale" is in
reality, all the way to the left. National often simply turned the
meter upside down to get the same effect. But.. its all a matter of
semantics.

Thanks fior the useful info. That is just what I wanted to know.

P.S. I had answered you at your persnal address, but the anti-spam system of
your Internet provider bounced my mail back. Perhaps you should tell that
bouncing back the good mails is not a clever way to avoid spam.
