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.
