97.307 Emission standards.
(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.
(b) Emissions resulting from modulation
must be confined to the band or
segment available to the control operator.
Emissions outside the necessary
bandwidth must not cause splatter or
keyclick interference to operations on
adjacent frequencies.
(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

(2) No non-phone emission shall exceed
the bandwidth of a communications
quality phone emission of the
same modulation type. The total bandwidth
of an independent sideband emission
(having B as the first symbol), or
a multiplexed image and phone emission,
shall not exceed that of a communications
quality A3E emission.
