Sec. 78.101 Power limitations.
(a) On any authorized frequency, the average power delivered to an
antenna shall be the minimum amount of power necessary to carry out the
communications desired. In no event shall the average transmitter power
or equivalent isotropically radiated power (EIRP) exceed the values
specified below.

(b) LDS stations shall use for the visual signal-vestigial sideband
AM transmission. When vestigial sideband AM transmission is used the
peak power of the visual signal on all channels shall be maintained
within 2 dB of equality. The mean power of the aural signal on each
channel shall not exceed a level of 7 dB below the peak power of the
visual signal.
