[Boatanchors] Band Width

[Glen Zook via Boatanchors]

Since commercially manufactured amateur radio equipment transmitters, with the exception of external r.f. amplifiers capable of operation on frequencies below 144 MHz, are NOT subject to certification (receivers capable of operating between 30 MHz and 960 MHz do have to meet certain 47 CFR Part 15 requirements), there are absolutely NO SSB bandwidth standards that have to be met by the manufacturer.
Like it or not, the individual amateur radio operator IS responsible for his/her signal quality and the manufacturer has absolutely no legal responsibility for the quality of the signal.  One would hope that the equipment is capable of meeting the technical standards set forth in 47 CFR Part 97 and 47 CFR Part 2.  However, under present regulations, the manufacturers are under no obligation to meet such standards but the individual operator is required to meet those standards.
Certification of amateur radio equipment, like is required for basically all other services (there are certain exceptions under 47 CFR Part 15), is not really desired because this would eliminate all modifications, home-brewing, and so forth by individual operators. Glen, K9STH

'Anything that causes a broader than normal SSB bandwidth (about 2.6-2.7

transceiver manufacturers are required to meet...."

What is the governing document  and regulation for this standard?
