Seeing that P25 Phase 2 is almost the same as DMR, how do they do it?! Phase 2 will do the same as DMR, use time slot 1 only on simplex. It will work, just only one time slot - one user at a time.

Keep in mind that P25 II TDMA is only capable of network repeater operation (read that "trunked"). Simplex is not supported on Phase II, as there is no way to accomplish the sync requirement for 2 subscriber sets in direct simplex mode, thus infrastructure is required.
