We present observations made with the Australia Telescope Compact Array(ATCA), the Jansky Very Large Array (JVLA) and the Giant Metre-Wave Telescopeof the radio source within the galaxy WISE~J071634.59-190039.2, claimed to behost of FRB~150418 by Keane et al. (2016). We have established a common fluxdensity scale between the ATCA and JVLA observations, the main result of whichis to increase the flux densities obtained by Keane et al. At a frequency of5.5 GHz, the source has a mean flux density of 140uJy and is variable on shorttimescales with a modulation index of 0.36. Statistical analysis of the fluxdensities shows that the variations seen are consistent with refractiveinterstellar scintillation of the weak active galactic nucleus at the centre ofthe galaxy. It may therefore be the case that the FRB and the galaxy are notassociated. However, taking into account the rarity of highly variable sourcesin the radio sky, and our lack of knowledge of the progenitors of FRBs as aclass, the association between WISE~J071634.59-190039.2 and FRB~150418 remainsa possibility.
