#1 is interesting because most other people are not seeing this. So I wonder if something could be wrong on your particular hardware or your settings, I wonder if you have done a factory reset in case any setting got corrupted??
After you suggestion, I did perform the factory reset. Initially the thump was a bit quieter but this was only due to a relatively low volume set after factory reset. When I raised the volume the thump is about as loud as before the factory reset. So no change here.
I can see the glitch on Audacity; it's there but I find it almost inaudible particularly when on the bands not on a dummy load. I also went back to earlier firmware versions back to 1_00_009 an the?size of the glitch was the same as on 1_00_014. So there is nothing in the firmware that has changed it, at least on my QMX here; which is also consistent with my own expectations since I have not (intentionally at least) changed anything in the code in this area.?
