This paper is one in a series in which studies of the radio continuum brightness distribution in bright, nearby spiral galaxies with the Westerbork Synthesis Radio Telescope (WSRT) are reported. The observing frequency is 1415 MHz and the bandwidth is 4 MHz. The synthesized beam is elliptical and the half- power beamwidths at full resolution are 23'' (RA) and 23''/sin sigma (Dec). Observations are presented of NGC 598 (M33), 4826, 3031 (M81), published results comprise all fourteen spiral galaxies brighter than Harvard magnitude 10.5 above declination + 15 deg . The observed distributions have been used to derive, apart from individual interesting features, three important parameters. These are the flux density of the nuclear source, the spiral arm component, and the base disk. (WDM)
