We report the first detection of radio emission from the reputedly jet-driving symbiotic star MWC 560, which is currently undergoing a multi-wavelength outburst (ATel #8653, #8832, and references therein). On 2016 April 4.94 UT, the Jansky Very Large Array (VLA, C configuration) detected MWC 560, unresolved with a flux density of 82 +/- 5 microJy at 9.85 GHz (X band, with 3-bit samplers to cover a 3.65 GHz-wide broadband). This constitutes at least an order of magnitude enhancement over a Jansky VLA non-detection that we obtained on 2014 October 2.45 UT, before the outburst. At that time the 2*RMS upper limit was 6 microJy in this broadband.
