Is averaging on the list for V 1.0 ?

There is a current feature for slowing down the frame rate that will make the display less "jumpy", but actual FFT display averaging is not slated for SmartSDR v1.0

I would imagine this would be implemented after or about the same time as waterfall, pan-fall, etc? (important, but B-list priority, after other crucial performance enhancements?)

Sorry to hear that this is not going to make 1.0. The jumpy/spastic display looks terrible in my opinion, and this is what the brand new owner is going to look at all day. Not only that, it's what the brand new owner's friends are going to look at all day. Lowering the FPS is a solution, albeit a poor one -- it makes it look like you have a computer that can't handle the load and are getting bad frame rates as a result.

To me, the nicest display ever is the 5000 with AVG on and the FPS set to 30. Beautiful, liquid traces that are just sexy. The current display is like staring into a 8kv arc, but without the ozone.

Paul liked what I sent in the video. We're going to try this change for v1.1 and see how folks like it.

Any chance the 2 averaging algorithms could be options? That would make it easier to compare them. (not sure how we could do it otherwise). Also if there are differing opinions on what is best, a user could pick their favorite.

BTW, the current averaging is nice and better than I'm used to. So if the new algorithms is even better that would be great.

Ask Steve for a link to a video demo. With that you can immediately see the difference. The new algorithm responds to signal peaks but retains the fluid decay of averaging. This has the benefit of seeing true signal peaks that are otherwise reduced through averaging.

Steve & Paul,
I would like to see it.....and maybe we can upload it for others to see. I have a YouTube channel where I have posted a few other Flex videos.

I would love to see it, too, if possible.

I agree, I use AVG for cw and digital. (don't do much SSB) find the display easy on the eyes, and very easy to precisely select the proper place to transmit.
After long hours of contesting, I find it EZ less tiring then that frenetic display you get when you first start the 6.5K.

First thing I do when starting SSDR is go to 'Display' and move the FPS way lower.

But then what do I know?
