True. This recent FCC citation does not address spurious emissions, just the suitability for the service to which the radios were marketed.I did not see anything related to output purity like spurious signals or high harmonic content. It apears they can still be used in the Amateur service...
However, I would not take that as a statement from the FCC that the subject radios "can still be used in the amateur service". §97.307(e) still applies to radios used in the amateur radio service.
