Uses 555 timer IC to make ST-6 autostart turn off motor of teleprinter if copying commercial station that does not drop its carrier when no text is being trans. mitted. Values shown for C1 and R1 give time of 15 s which, added to 25 s of ST-6 delay, gives about 40 s to turn off in presence of steady mark tone (carrier only). Useful when copying weather and press reports.-R. Bourgeois, Stop That Autostart, 73 Magazine, May 1977, p 47.
