The commercial station is two months in the making and a month on air and has committed advertisers, including Miller Corp., Sapporo, Bud Light and Heineken. It has expanded the Globe’s 21- to 34-year-old male demographic, hence the alcohol advertising, Desisto said.

RadioBDC isn’t for national advertisers looking for an expansive platform, she said, but for companies looking “to make a splash” in the Boston region.

DJs are manually uploading music into RadioBDC computers, often bringing in CDs from home to build a music library from scratch. The station faced costs like constructing a new studio, obtaining music rights and paying staff salaries but saves in marketing costs, utilizing the Globe’s established ad and event staff. And across the hall are Globe journalists, ready to discuss morning news on air.

“We’re going to be able to do a lot of things here that we weren’t able to do at our last places because of resources, technology, money,” said Julie Kramer, one of the WFNX DJs who moved to RadioBDC. “We’ll be able to take this to a new level.”

The endeavor faces challenges sustaining advertisers, reaching audiences who don’t own smartphones and competing against iPods and online stations, said Justin Ellis of Harvard University’s Nieman Journalism Lab, who has written about RadioBDC.

“At least in the initial phase and the setup, everything seems to be going their way,” Ellis said. “But the question is: Will it work in the long term?”
