I've only begun listening to WUMB recently, but I've been aware of it for years. I couldn't get the signal in my home or car. Then my son's family moved near Worcester and I found the signal while driving there. Sometimes during the drive I listen to it, but if I don't like what the host is playing I switch to the classical station. I'd I dont like that, I'll play a CD. U Mass-Dartmouth has a station that I could easily pick up at home and in my car when driving locally. While it is not all folk, I know when to listen. Then it sold its signal and now only streams. I can't listen to it in my car. It exhausts my phone's battery too quickly, and my tablet is wifi only. I sometimes stream it if I'm home when the programs I like are on.
Beware: if U Mass-Dartmouth sold its signal to get money, U Mass-Boston may do the same!
