Reverse Burst is NOT only used with reed type PL (ctcss) units. Reverse Burst will work with any type of detection system, mechanical or all solid state. The timing of the non mechanical units is typically a little less than the mechanical counterparts, as some older reverse burst generation will actually cause the PL sense of a unit like a Com-Spec TS-64 to stop decoding and then begin again before the encoding transmitter drops out (undesirable). In the Motorola Micor, the tone phase is rotated 120 degrees for about 180 mS, then the tone ceases and the transmitter carrier continues for several more mS, then drops totally.
