We discuss the radio spectrum of Sgr A in the frequency range between ≈ 1 GHz and ≈ 1 000 GHz, show that it can be explained by optically thin synchrotron radiation of relativistic electrons, and point toward a possible correlation between the spectrum of Sgr A and larger-scale (≲ 50 pc) radio emission from the Galactic Center region.
