Hi Ahmed
I have run the same tests in the last 2 days on my QMX+.? I found I had some weird pictures too.? Firstly I reloaded the firmware after reading an earlier blog.? This fixed the filter tests.? However the SWR test is still wrong and I believe it is because on the higher bands my QMX has a very low output power (one of my problems) and the SWR can't be properly measured.? There are quite a few examples of filter plots on this site to give you an idea of what others are finding.? I hope this helps.
Regards
Greg
