The LINER galaxy NGC 1052 represents the rare case of a radio-loud AGN with a prominent compact jet structure and a broad Fe K line. As part of a multi-mission monitoring program begun in 2005, including VLBI radio observations and several pointings with different X-ray missions, a 101 ks Suzaku spectrum has yielded the highest signal-to-noise X-ray spectrum of NGC 1052 to date. We present the results from this observation as well as a comparison of the state of the disk during different epochs based on past data. The X-ray data allow us to differentiate between competing continuum models and to trace changes in the morphology and strength of the iron line and surrounding continuum. We particularly focus on what the X-ray results imply about the nature of the accretion flow.
