The supernova remnant IC 443 has been mapped at 151 MHz using the Cambridge Low-Frequency Synthesis Telescope with a resolution of 1.2 x 3.1 sq arcmin (RA x Dec), and at 1419 MHz using the Cambridge Half-Mile Telescope with a resolution of 2.1 x 5.4 sq arcmin (RA x Dec). These observations detect nonthermal emission from the region of the faint optical filaments to the north-east of IC 443. Comparison of the 151-MHz and 1419-MHz maps reveals a region in the south-east with a flatter than average spectrum, and also suggests that the brighter north-east of IC 443 has a flatter spectrum than the faint south-west. This variation, and a possible spectral break for the north-eastern region, are discussed with references to the mechanism of particle acceleration. 151-MHz observations of S252 (3C 153.1) are also presented.
