You didn't say whether you were the original owner, but it sounds like
the older unit has either been modified by a previous owner somehow or
has a problem that manifests itself as a slower tuning rate. I have an
older and a newer as you do and 10KHz per rotation is what they both do.
I am not aware of a specific mod to slow the tuning rate down, but
perhaps a change of encoder did the trick. You might pull the front
panel on each and see what differences you can find.
I have been using my 2000 vintage 1000D since I bought it new, and
acquired the older one a couple years ago. I have been using both of
them so much that I guess I am used to the tuning rate. Here are some
suggestions that may help:
1. If you are running writelog, and you are using a mouse with a
center wheel, turning the wheel tunes the active radio! I discovered
this by accident a little while back so I don't know when they added
it. The rate is 10Hz per wheel click.
2. Use RIT+XIT both on to fine tune (I don't do this but it would seem
it would work?)
3. What I do most of the time is just rest my hand on the table
underneath the knob and use my index finger to gently feather the
knob. I guess I have just done this enough that the practice has
worked. I find that I can snap the knob to the right place by ear. I
don't consider that I have any innate talent for this, I just do it
because I have to.
Just by the way, I added the InRad roofing filters to both rigs, and
the improvement has been dramatic. I have found that 'splatter' of
nearby stations doesn't bother me anywhere near as much as it used to,
and this includes robots. And as a result I seldom if ever reach for
the shift knob anymore.
Hope some of the above is helpful - jeff wk6i
