FEDERAL COMMUNICATIONS COMMISSION:
TRANSMITTER RULES AMENDED
The Commission has amended its rules to eliminate the
required annual measurement of transmitter power,
frequency and modulation, and to specify transmitter
power in terms of output power for licensees in the Public
Safety, Industrial, and Land Transportation Radio
Services.
The action was the result of a rulemaking procedure
initiated October 29, 1976 on request of HT & B
Electronics.
Under the rules, which amend Parts 89, 91, and 93,
licensees will continue to be required to operate their
transmitters within the specified technical parameters.
For the sake of convenience and simplicity of transmitter
power measurement, the FCC specified that in the future,
transmitter output power, rather than the direct current
input power to the final radio frequency stage, be the
standard parameter used to indicate transmitter power.
The FCC defined transmitter output power as that power
measured at the transmitter output terminals when
connected to a load of the impedance recommended by
the equipment manufacturer.
