N2 - We re-examine a series of archived centimetre radio-continuum observations (λ = 16, 6 and 3 cm) focusing on NGC7793 using the Australia Telescope Compact Array. These new images are both very sensitive (σ = 0.011 mJy/beam) and feature reasonably high angular resolution (down to <3"). Using these images, a total of 76 discrete radio sources are identified, of which 57 have been classified. We also studied the radio component of the micro-quasar NGC7793-S26 which shows two distinct regions of somewhat steep spectral index (α) between −0.3 and −0.7.
