We used the 32m radio telescopes of Istituto di Radioastronomia (INAF-IRA) in Medicina and Noto as a two-element very long baseline interferometer to search for a possible radio counterpart of SN2013ej, a type IIP supernova (CBET #3606, ATel #5228, #5229, #5230, #5237, #5243) in M74. The observations were conducted at 6.7 GHz on 2013 July 31.3 UT, 6 days after the first optical detection reported in CBET #3609. The Medicina-Noto baseline length is 893 km (projecting as 19.6 Megawavelength). No radio emission from SN2013ej was detected with an upper limit on the correlated flux density (5 sigma detection limit) of about 35 mJy. Extragalactic radio sources 0127+145 and 0528+134 were used as fringe finders and flux density calibrators.
