EXPANDED COVERAGE FOR A CITY ON THE RISE
KRTU’s New Broadcast Tower
In April 2017, KRTU started broadcasting at 30,000 watts—a significant increase from its previous HD terrestrial signal strength of only 8,900 watts.
The future of KRTU as a world-class radio station is dependent on audience reach and the KRTU Tower Initiative ensures that FM 91.7 can continue to thrive in today’s increasingly competitive radio and media markets.
