KDSM-TV, the Fox affiliate in Des Moines, Iowa, is back on the air thanks to rival station WHO-TV, which is letting KDSM broadcast on its digital channels.

A line to KDSM’s transmitter failed on May 17 and efforts to repair the transmission line have been delayed.
In order to get a high-definition picture, KDSM is displacing both Antenna TV, which had been on digital channel 13.3 and This TV, which had been on 13.4. Both networks will be restored when KDSM returns to channel 17.
