Maybe, YMMV.
If clipping is an issue, it would seem expedient to keep RFI to a minimum to help the dynamic range to be as useful as possible.
Perhaps the shielding does mitigate the RFI, but I donāt have a Radarscape, nor access to a GHz class spectrum analyzer, to investigate. The Reddit poster (above) recommends shielded Ethernet cables, if youāre using that medium. I tried RotM Cat5, and the BBB seemed to radiate UHF RFI from the cable, and thatās after completely disabling HDMI - another violent source of VHF/UHF RFI on my unit.
Again, I donāt have a GHz class analyzer, but Iām not partial to the discounting of evidence, even when it is out of band.
My BBB doesnāt have a metal case. An RFI engineer working for AAI once told me, eons ago, that the only way to really control noise is to enclose electronics in a box with no openings. Perhaps, but Iām not an EE, and I got the gist of a Faraday cage from University physics.
My BBB is an early model, and may be worse than the newest redesign (Rev C). However, the Reddit poster provides evidence that correlates with my experience.
I am by no means an expert in credentials, experience, or education; but I am curious within the bounds of my means.
I have no interest in buying a $100k network analyzer to fully investigate, and assist in potentially mitigating, the condition I hypothesized here. JFFT
