Structure for controlling the output power from a microwave transmitter uses a digital value transmitted under control of software to an outdoor unit of a transmitter thereby to allow the power output of the transmitter to be changed under control of the software. The digital value is generated by an indoor unit of the transmitter or a remote transmitter across a link or elsewhere in a network. Other parameters of the transmitter can also be varied under control of the software. These parameters include the frequency and muting as well as the generation of test signals at the transmitter. In one embodiment, the outdoor unit contains a non-volatile memory in which the digital value is stored and a microprocessor which generates a control signal from the digital value to set the output power of the transmitter. Software executed by the microprocessor can correct the control signal for temperature so that the output power of the transmitter does not change when outdoor temperature changes.
