Boise State Public Radio's KBSJ, KBSS, KBSW and KBSY are back on the air.
Original Post: The College of Southern Idaho is upgrading an Internet circuit, which has knocked several Boise State Public Radio stations off the air.
KBSJ in Jackpot, Nev., KBSS in Sun Valley, KBSW in Twin Falls, and KBSY in Burley have been off air since 1:30 p.m. Tuesday because of the work at CSI.
The college says work will continue for at least another hour.
