In this chapter the radio properties of the Galactic Center black hole (Sgr A*) are reviewed: variability, size and position from VLBI (Very Long Baseline Interferometry), spectrum, and polarization. Radio and X-ray emission are discussed within the framework of black hole plasma jet models and simple equations for the emission are derived. It is also shown that the radio emission can be used to actually image the event horizon of the black hole in the near future.
