The 1050 hz tone is the original arert tone that was used before the SAME system was installed. It is still transmitted with a duration of 8-10 seconds,is not area specific and will give a warning for the whole coverage area of the station, sometimes as much as 5000 square miles. Generating a SAME tone is not for the faint of heart. It is digital and has such oddball parameters as 520.83 bps data rate, a digital 1 = 2083.3 hz , a digital 0 = 1562.5 hz.
