The young core-collapse supernova SN 2022crv (=DLT22d, ATLAS22gdi) in NGC 3054, originally classified as a type Ib event, has been observed with the Australia Telescope Compact Array (ATCA) at 5.5 and 9.0 GHz on 1 March 2022 09:00-13:00 UT. Clear radio emission was detected at the reported location, with flux densities of 0.7 mJy and 0.5 mJy at 9.0 and 5.5 GHz respectively, suggesting the radio emission may be yet to peak at these frequencies. Adopting a host galaxy distance of 34 Mpc from the NASA Extragalactic Database (NED) this implies a 5.5 GHz luminosity 10 days after discovery of 7E+26 erg/sec/Hz. We would like to extend our thanks to the ATCA staff for enabling these observations. The ATCA is part of the Australia Telescope National Facility which is funded by the Commonwealth of Australia for operation as a National Facility managed by CSIRO. We acknowledge the Gomeroi people as the traditional owners of the Observatory site.
