You can set an alarm to wake up to WGTS on your Amazon Echo device.
You can tell Alexa when to wake you up and what music you want to hear. For example, you can say, "Alexa, wake me up to WGTS every morning at 6:20 AM." Or, "Alexa, set an alarm to play WGTS at [time]."
Note: Alarm clocks need to be set by voice and can't be set in the Alexa app.
See your Echo device manual for further instructions on other features.
