  An effective field theory framework is used to investigate some
Lorentz-violating effects on the generation of electromagnetic and
gravitational waves, complementing previous work on propagation. Specifically
we find solutions to a modified, anisotropic wave equation, sourced by charge
or fluid matter. We derive the radiation fields for scalars, classical
electromagnetic radiation, and partial results for gravitational radiation. For
gravitational waves, the results show longitudinal and breathing polarizations
proportional to coefficients for spacetime-symmetry breaking.
