Our VLA observations of the XMM-Newton/Chandra 13hr deep survey field ( see Page et al. , this proceedings ) result in one of the two deepest 1.4GHz radio maps ever made .
Within the 15 ^ { \prime } radius field covered by the deep X-ray data ( 0.19 deg ^ { 2 } ) , a total of 556 radio sources are detected , down to a 4 \sigma flux limit of 28 \mu Jy .
Of the 214 Chandra sources , 55 have radio counterparts .
The sub-arcsecond accuracy of the VLA and Chandra positions enable us to determine with high confidence the sources common to both surveys .
Here we present the relationship between the X-ray and radio source populations at the faintest radio flux limits yet probed by such a study .
We discuss how the X-ray/radio relationship differs as a function of optical morphology , ie between unresolved ‘ stellar ’ objects and well resolved galaxies .
We then discuss the origin of the X-ray and radio emission , ie AGN , starburst or a mixture of both , in these two classes of object .
