We have observed two radio sources that are positionally coincident with the recently detected high-energy neutrinos IceCube-201114A (GCN #28887) and IceCube-201115A (GCN #28889) with the 100-m telescope of the MPIfR (Max-Planck-Institut fuer Radioastronomie) at Effelsberg on Nov 17, 2020, at 4.85GHz and 21.15GHz. The radio source PKS 1256+018 (coincident with IceCube-201114A) is associated with the brightest component in the region of interest of the Very Large Array Sky Survey (VLASS, Gordon et al. 2020, RNAAS, 4, 175; see ATel #14177). The radio source NVSS J065844+063711 (coincident with IceCube-201115A) is associated with the cataloged Fermi-LAT gamma-ray source 4FGL J0658.6+0636 (see ATel #14188). We report the following contemporary flux densities: PKS 1256+018: (198 +- 10) mJy at 4.85GHz and (84+-10) mJy at 21.15GHz. NVSS J065844+063711: (26 +- 3)mJy at 4.85GHz
