Including maintaining a *clean*, narrow signal that does not use
half again as much spectrum as a reasonable communications grade
signal as defined by ITU (and NTIA).
97.3(a)(43) Spurious emission. An emission, or frequencies outside
the necessary bandwidth of a transmission, the level of which may be
reduced without affecting the information being transmitted.
(SSB) Phone = 2K80J3E => Necessary bandwidth 2.8 KHz. Emissions outside
2.80 KHz = "Spurious emission"
97.307(a) No amateur station transmission shall occupy more bandwidth
than necessary for the information rate and emission type being
transmitted, in accordance with good amateur practice.
97.307 (c) All spurious emissions from a station transmitter must be
reduced to the greatest extent practicable. If any spurious emission,
including chassis or power line radiation, causes harmful
interference to the reception of another radio station, the licensee
of the interfering amateur station is required to take steps to
eliminate the interference, in accordance with good engineering
practice.
SSB greater than 2.8 KHz is neither "good engineering practice" nor
"necessary for the information rate and emission type being transmitted".

Can we dial down the rhetoric? Calling something outdated is fine.
Infantile and Childish is a tiny bit much.
