Beginning March 31, WLTR (91.3 FM Columbia) will experience outages as our crews perform upgrades to our broadcast transmitter. For the safety of our tower crew, we will broadcast at low power during this time. Our stations may experience intermittent outages as this process occurs, with the possibility of going off the air completely for extended periods. We hope to keep these interruptions at a minimum. You can stream stations at southcarolinapublicradio.org.
