NGC 3894 is a 13th magnitude E/SO galaxy (de Vaucouleurs, de Vaucouleurs & Corwin 1976; Nilson 1973) whose recession velocity (Kelton 1980) implies a distance of 44 Mpc if Ho=75 km s−1Mpc−1. The radio emission from NGC 3894 is compact-core-dominated and, as shown in Fig. 1, this compact core is surrounded at 1.5 GHz by weak diffuse emission with a characteristic size of ~2 arcmin (26 kpc) (Wrobel & Heeschen 1983). If the compact core radiates isotropically, then its radio luminosity is ~1040 erg s−1.
