Greater Media’s WBT(AM) was the first class A station in the U.S. (and likely the world) to transmit in all-digital HD mode. They are also the only station to date to accomplish digital AM transmission via “skywave,” which enables clear and broader transmissions of signals.

Why is it important?
These tests demonstrated the performance of all-digital AM in a “real world” environment. These results will help AM broadcasters consider whether transitioning to an all-digital transmission scheme would be feasible and help them to understand the tradeoffs between the current analog and hybrid digital systems and the all-digital system.
