Recent results from the Compton Gamma-Ray Observatory (CGRO) show that all of the gamma-ray detected quasars and active galaxies (AGN) are radio-loud. These discoveries, and previous statistical studies with results from the Einstein Observatory suggest there is a strong relationship between strength of high energy emission and radio emission especially for compact, flat radio spectrum AGN. The synchrotron self-Compton process (SSC) could explain such a connection. We have observed a sample of flat spectrum radio loud AGN with VLBI, the VLA, the JCMT submillimeter telescope, UKIRT,and ROSAT. In addition, several of the objects have been detected by the EGRET instrument on CGRO. We use these data to compare the observed spectra with those predicted by the SSC mechanism.
