The Public Radio Satellite System has updated its “Public Radio Resource Guide,” listing everything from technology and equipment services to training, funding and underwriting, membership organizations and conferences. “There is an overwhelming volume of information online of interest to the public radio community,” Pete Loewenstein, NPR v.p. for distribution, said on the Radio World website. “Our new guide is an effort to put some of this information in a format that’s easier for stations and producers to access.” And it’s free.
