I still don't get this "business" of radio. If an owner, e.g., Beasley, doesn't want to invest a dime in an AM station when they have FIVE FMs to occupy their attention, then why not just turn in the license for 1330 AM?
Granted, I speak with forked tongue, because where I reside, I'm right between the coverage edges of both 106.1 FM Bloomberg signals, so, if I wanted to hear Bloomberg in my area, I'd need 1330 AM. I don't have HD either in my car or at home. I haven't tuned in to 1330 AM since the audio complaint was reported herein. I'm betting Eli captured the essence of the audio chain issue very nicely. There's also the possibility of a bad satellite receiver or IP link 1330 uses to connect to Bloomberg.
Bloomberg pays them money for it. They can do the minimum with it which is basically making sure the station works, follows the FCC and the EAS functions correctly.
Key thing is they make money. Format didn't even really change. It was leased Ethnic before to various broadcasters, now Bloomberg is leasing the station 24/7.
