Cyg X-3 is an unusual X-ray binary which shows remarkable correlative behav
ior between the hard X-ray, soft X-ray, and the radio. We present an analys
is of these long term light curves in the context of spectral changes of th
e system. This analysis also incorporates a set of pointed RXTE observation
s made during a period when Cyg X-3 made a transition from a Baring state (
including a major Rare) to a quiescent radio state.
