Here is the original statement:
Up until a day or so ago I was
able to smoothly change the freq on my Flex 5K (1.18.0) by left
clicking and holding while sliding across the panadapter. Now all of a
sudden it will slide part way and then hang up.
Here is your answer:
Is spur reduction turned off?
The original problem didn't mention spur reduction at all, but rather
mentioned the fact that that panadapter would hang when dragging it with the
mouse. In response to that, you brought up spur reduction implying that
there is a connection between the two. And apparently turning spur
reduction on fixed the problem with dragging the panadapter to a new
frequency. I commented that dragging the pan adapter worked the same for me
both with and without spur reduction. My comment had nothing to do with
spur reduction itself, but rather on the behavior of the panadapter. You
are the one who made the connection between the panadapter dragging behavior
and spur reduction.
So let me rephrase my question in a way that you may understand. What
prompted you to ask about spur reduction when the direct question had
nothing to do with spur reduction, but rather with an unexplained hanging of
the panadapter when dragging it with the mouse? I fail to see the
connection that you yourself made. To me the implication of your question
is that there is a difference in pan adapter behavior when dragging it with
a mouse that is dependent on the position of the Spur Reduction button.

Clay,
You are missing the point. You asked about dragging outside of the
panadapter and the frequency still being changed (see where I reposted your
quote). That has nothing to do with Spur Reduction being on or off.
The state of the Spur Reduction control (on or off) has a secondary effect
that manifests itself as a jittery display (not a smooth drag) and/or audio
drop outs when dragging the console to tune the radio and it is related to
the algorithm used to render the Panadapter when the DDS is being changed.
My original reply to Tim contained a link to the Knowledge Center that
describes the advantages and disadvantages of using Spur Reduction. Refer
to the last paragraph.

OK, but wasn't the original problem in this thread the fact that Tim
couldn't drag the panadapter without it hanging when Spur Reduction is off?
He turned Spur Reduction on and fixed that problem, and now you're telling
me that Spur Reduction has nothing to do with dragging the current
frequency. If that's the case then why did you ask him if Spur Reduction is
off? Exactly what is the limitation when Spur Reduction is off that Tim was
experiencing in the original question?

"I can "click and drag" the panadapter for the full width of my computer
screen (even outside the PowerSDR window once I start dragging)"
It a "feature" of the software.
Spur Reduction has nothing to do with the dragging of the spectrum. Having
it off generates a ton of DDS MIDI control messages and screen re-paints
that cause the jittery display when dragging. Turning SR on reduces the
number of messages sent between the radio hardware and PowerSDR.

I'm confused. I can "click and drag" the panadapter for the full width of
my computer screen (even outside the PowerSDR window once I start dragging)
regardless of the Spur Reduction setting. What am I missing here?

Now I feel foolish.. Yes it was off and when I turned it on it works
like I was accustomed to.
Thanks Tim...

Wasn't really sure how to title this. Up until a day or so ago I was
able to smoothly change the freq on my Flex 5K (1.18.0) by left
clicking and holding while sliding across the panadapter. Now all of a
sudden it will slide part way and then hang up. If I let up on the
mouse and click again I can continue fine.
I haven't changed anything that I can recall. Changing the freq this
way on "Betty" works fine, no problems. The CPU usage is down around
10% to 15%. It doesn't change when the slider hangs up.
Any suggestions?
Thanks
Tim
