LimeSDR mini in black/green aluminum housing - shielding


I found my LimeSDR mini in the black/green aluminum housing showing effekts like from bad shielding, including varying RF behavior when touching the housing and such.

Now I opened it and found it being completely clored and insulated, no ground connection at all to the board. This is a quite bad idea, and I will try to change this and see if it improves…

With best regards


Is this the esa case, like I have on the Mini? I think it’s over-heating my mini as well, so I am considering removing it.

How did it go on your end? Is the SMA port insulated too or is that grounded to the case at least? I will have to test mine.
