Weekends have a less structured schedule, with an emphasis on world and electronic music, as well as children's, sports and specialty programming.

WRIU also operates RIU2 (formerly Studio B), an internet-only station with an air staff composed exclusively of URI students and a freeform format.

The original purpose of RIU2 was to train and prepare DJs for the transition to FM, but the diversity and quality of shows on RIU2 have made it a significantly popular internet radio station in its own right.

The station signal was 10 watts and coverage was generally just nearby to the Campus, sometimes reaching farther.

When the station wished to expand in about 1971, installing a more powerful signal with updated facilities, the U.S. Federal Communications Commission (FCC) requirements included surveying the current and potential audience- mostly URI students- to show support for FCC approval of such expansion.
