Leroy, I'm sure others can explain it better, but... Reverse burst was / is used by Motorola and others to eliminate "squelch crashes" at the receiving end of a comm circuit. It works like this: after a transmission, the transmitter stays keyed momentarily, during which time an out-of-phase version of the PL tone is transmitted. This out-of-phase tone causes the tone decoder at the receive end to shut off audio before the transmitter carrier disappears. Someone will correct my errors here :) This might help: http://www.repeater-builder.com/rbtip/reverseburst.html Paul
