A method and apparatus mitigates spurious transmissions. An offset local oscillator signal is generated that is at a frequency that is offset from a nominal transmit channel carrier frequency by a spurious mitigation offset. An information signal is generated that comprises a series of modulation symbols and has a transmission bandwidth at baseband. A configured offset information signal is generated from the information signal, wherein the spectrum of the configured offset information signal is offset from DC by a channel configuration offset, and is further offset by a negative of the spurious mitigation offset. The offset local oscillator signal and the configured offset information signal are combined using a mixing technique. The spurious mitigation offset is zero when a spurious condition does not exist and is non-zero when the spurious condition does exist.
