Morse code lives on in the form of Station Identification [1]. By law, radio stations are required to periodically transmit identifying information. The announcer on a commercial radio station will typically say it, but there are lots of Land Mobile Radio stations out there that don't have a person in the loop.

For an unattended station, by far the cheapest and easiest thing to do is program the base station to periodically transmit the station ID as a burst of Morse code. It's not that many years since I wrote code to transmit Morse, that code being embedded in radio base stations that are still being sold.
