Smoothing filter or averaging for the data trace

Makes signals more visible in noise, reduces operator fatigue for prolonged usage.

    The variable averaging control on PowerSDR's pan adapter is a very useful feature. It's much easier on my eyes and it also made measuring the width and ripple of a received signal's spectrum stand out. Variable averaging can also be done with a 2nd trace of a different color. Anybody else miss those smoothed pan traces??

    It is a wonderful option on PSDR not only for the panadapter and pan-fall, but also in the "spectrum" display for both receive and transmit. I find that I can adjust my transmit audio EQ fairly closely to what I want by using the averaged visual clues in the "spectum" display. It is very useful to me. I hope it makes the list on future revisions. (And I can't wait to try it when my 6500 arrives!)

    I wish to add my agreement with the need for averaging the pandapter trace - like PSDR. It is more than difficult to effectively use the un-averaged view when try to locate a vacant spot for a group rag-chew. The wild gyrations of the trace mask the visibility of a weak signal representing a QSO that II would rather not fire up on top of their QSO. While I really consider this a necessity for me to ultimately drop PSDR I totally agree that it should stand behind a number of bigger warts and blemishes that are being straightened out. Could we see it somewhere on the roadmap at least?

    My Yaesu FTDx9000 has several display modes including the trace averaging which I prefer. After inquiring about the FLEX approach to averaging, Ned / K1NJ send me some screen shots from his Flex5000. They demonstrate how the averaging helps with weak signal CW DX in PowerSDR. It works as good as or better than my FTDx9000. See the snapshot below. I added the lines and arrows to show the two modes. In the screen shots the signal is a constant carrier about 10db above the noise. For weak signal DXing I think the difference is huge and much better than simply slowing the FPS rate. Other thoughts? Do you agree? Thanks to Ned for the pictures and insight. Regards, Al / NN4ZZ ************ CLICK to enlarge ***********

    I wish to add also my agreement with the need for averaging the pandapter trace like PSDR. Cheers, Emil, de DL8JJ

    Has anyone heard whether the "trace averaging" is going to be implemented/incorporated in one of the planned roadmap features? - waterfall? - panafall? - scope? Regards, Al / NN4ZZ

    Request for trace averaging fulfilled Dec 20 in Beta 1.0.24. The interface control from the front panel is good, better than menu control on PowerSDR. It is more useful at all panadapter bandwidths that way. Thank you very much. Ned, K1NJ

    I have to say that Flex's implementation of *variable* averaging is pretty dang awesome. Great job guys, exceeded my expectations!

    My only disagreement with these praises is they understated how good the averaging implementation turned out. Very worth waiting for. Now lets have it in PWRSDR!
