How does EchoStation decide when to play an announcement?
Each announcement you set up with EchoStation has a pre-set schedule. You have a lot of flexibility in setting up a schedule – hourly, daily, weekly, monthly, or on specific days of the week or month. EchoStation keeps track of the last time an announcement played, and the next time it’s scheduled to play. When the scheduled time arrives, EchoStation checks to be sure the frequency isn’t already in use. If it has been quiet for 60 seconds, it keys the transmitter and begins playing the announcement, along with a CW ID underneath. If the frequency remains busy for a long time, EchoStation will (optionally) cancel the announcement, and re-schedule it.
