Is anyone familiar with the adjust mode in the service manual for the
950sdx?

My I.F. VBT is way off. I got to the adjust mode, menu 6 as it
indicates,
get a reading of 90 or so at center-but must go fully clockwise in
order to
pass the cw signal. (230 or so) I cant understand what they mean in
the
manual about "how" to adjust the setting and save it.

It seems gibberish to me.

I cant hear any cw signals through my 500 Hz 8.83 filter unless I move
the
I.F. VBT fully clockwise.

Any help would be appreciated, Please note new email address

Hi, all concerned:

Could this be a "-1"-filter-suffix vs " "-filter-suffix problem, ie,
differing center frequencies? Eg, the '440 had a YK88CN and the '850 had a
YK88CN-1, differing by a half-KHz or so in c-f and having the same b-w.

Not this time.

Thanks for the interest.

I got the adjust info from a good hearted Ham......no change.

Does anyone know which V.R. to adjust to center the VBT pot?

I am looking for it in the service manual, but not having much success.

I got a better copy of the schematic. It appears all is digital in the
adjustment of this control.

Perhaps I am missing something.

When using 2.7 or 1.8 kHz filters in CW mode, I still have to turn
I.F.VBT way to the right to get full strength cw signals.

When I add 500Hz filter, it MUST be within one or two clicks to hear
anything...just what I would expect.

Anyone have any ideas or insight as to what my brain is not
comprehending here?

All is appreciated.
