Of course, you never | | hear the other person talking on your trunk. | | | | When you start to talk, however, the TASI controller has to find an open| | trunk for you. Because of this delay in finding a trunk, some of your | | speech is lost; this is called clipping. | | | | If you were transmitting data over a trunk, clipping would really fuck | | up the data. So, there is something called a TASI locking frequency which | | keeps the TASI from putting anyone else on your trunk or you on anyone | | else's trunk. In any case, the frequency is 1850 hz, sent before the | | transmission). | | | <=-=*=-------------------------------------------------------------------=*=-=>  --------------------------------------- Enter (1-28, M=Menu, Q=Quit) :
