The paper presents radio brightness curves for an area of the galactic disk in the anticentre in the direction of PKS 0607 + 17 at decametre and centimetre wavelengths as obtained with the UTR-2 and RATAN-600 radio telescopes, respectively. The nonthermal source PKS 0607 + 17 is rather regarded as an independent supernova remnant (SNR), than as a part of the more extended remnant Origem Loop. The flux density of PKS 0607 + 17 is 28 Jy at 3.95 GHz and 146 Jy at 25 MHz; the average angular size is about 150'. The flux densities of another extended source, presumably also a SNR, GR 0625 + 16, are 7.5 and 80 Jy, respectively, at the same frequencies. Low frequency scans show several weak extended H II regions in the vicinity of PKS 0607 + 17 with emission measures from 90 to 200 pc cm-6. Our results do not seem to support the existence of a gigantic SNR like the Origem Loop.
