Possibly true. However, as a de-facto self-policing Radio Service, and in
the spirit of Elmering, it can sometimes to be helpful to discuss
long-propagated misconceptions, misunderstandings and misapplications of the
rules we operate under.

This is true of both operational and engineering practices. For instance,
many experienced radio amateurs still believe that there is a lower FCC
standard for spurious emissions on HF QRP transmitters than for those above
5W. That changed back in 2003, and now all HF transmitters must be at -43
dBc or better. That's 20 times (13 dB) tighter than the old spec. There are
exemptions for transmitters produced earlier, but those "placed in service"
after 1/1/2003 must meet the new, tighter spec. (see Part 97.307)

This means for example, that an amateur home-brewing from an older schematic
must make sure the finished transmitter incorporates sufficient harmonic
filtering and suppression of other spurious signals to meet the new spec.

It's not so much being a self-appointed lawyer, as helping our fellow
amateurs with opinions and advice that hopefully lead to good operating and
engineering practices. I know that I have learned a lot from those who have
Elmered me. I am constantly learning from those amateurs around me who are
more versed in areas than I am, including many on this list. Perhaps, in
some small way we can each learn from and help each other to promote a
culture of high performance in the Amateur Radio Service, a hobby we all
love.
