erratic compression slider

Jim McLesterJim McLester Member

If the PTT is activated too soon after moving slider the slider will move erratically with each PTT until there is a 1 or 2 second delay. Problem is intermittent. It was doing this yesterday evening and again today until I started trying to define the conditions under which it occurs. It is now not doing this game. Will add info if / when it returns.

    Yes it will. You have to give the radio time to receive the new compression command and process it. We are looking at a way to mitigate this behavior, but for now it is "how it works".

    Tim, that may well be the problem. However it does jump around to values that don't (to me) follow completely with that cause. I concede that with a 10 second delay it doesn't act up. The amount of "noise motion" seems to decrease with longer wait times!

    I'm sorta glad to see someone else is having this problem, but it is an annoying problem. Setting compression usually involves changing the setting, testing, and changing again in rapid order. Maybe a TX inhibit with a pop up modal window would be helpful?

    Changing the compressor setting requires sending a large amount of parameter data into the DSP module using a relatively slow serial data path. It is definitely not what we want, and we have been working on this problem for some time now, but have not yet found a suitable solution. It is definitely on the list, though! Jim WD5IYT

    The 1-2 second delay works, but sure was acting really weird before I knew that. Really an unexpected side effect. I think this should make it into the release notes caveats for other folks who might not be aware.
