Re: How well was the PC prepared?
Fine mesh over the holes works. The SDRs only work up to 1.7GHz away even that would allow larger holes than on a perforated Sky dish. (Small enough so it looks solid at 12.6GHz, but poor reflector at 20GHz). C band "Mesh"/Perforated dishes have bigger holes as maximum is less than 4.5GHz.
A lot of gear is badly screened, shielded or filtered. The FCC and CE RFI tests are both too lax and also often not realistic test scenarios (RFI from electronic ballasts or SMPSU radiated by lighting wiring that tends to be a loop, "power line ethernet" that are really transmitters and pass by only testing one or having no data). Sometimes after the FCC / CE approvals are obtained they leave out the filter parts to save money as there is little to zero in market retail sales testing.
