Mark Connelly at the Boston Radio Interest mailing list reports on a new station: WZBR, "Boston's Real Jazz," 1410 on your AM dial:
Music was about 80% instrumental 20% vocal. A number of jazz styles were played covering from '40s up to contemporary hip-hop / jazz fusion.
The station is licensed to Dedham but is actually using a transmitter and antenna off Sprague Street in Readville, he says. It's not audible everywhere in the Boston area, which might be due in part to its power - 610 watts daytime and 25 watts nighttime (by comparison, WBZ is 50,000 watts).
