Did you actually see the spurious emissions on a spectrum analyser?

The old Baofengs had that problem, not Quansheng which are actually clean and the harmonics are within FCC specs.

Another issue is people were “testing” them using an RTLSDR which very easily gets overloaded and shows harmonics where there are none. Even my local FM station shows up on my SDR at frequencies I know they’re not actually transmitting on.
I admit that I have not. But I have used it near other equipment and it causes interference. My Kenwood HT does not.
