I have a Cerbo GX Running in my Battery compartment, I've found that RFI on my Ham radio predominantly between 14Mhz - 30 Mhz is originating from my Cerbo GX.
I have tried unplugging different cables, and it seems that rather than being any one thing, it's cumulative from a variety of the cables connected to the device.
I have put clip on ferrites on most of the cables, these have not made much difference. I'm wondering whether more substantial Ferrites will make a difference or whether the internal components of the device are directly causing the issue.
Also considering putting the unit in a metal shielded case. Anyone else had issues like this, if so how did you fix it ?
