Under the TSYS objects tab, click "Trunking Tables," and then click the drop-down marked "'Standard'" band plans." You'll see "800 MHz rebanded" among the choices. This also may help:WIN500 - UtahRadio
Glad to be able to help. Win500 can seem a little intimidating at first, but once you use it a bit, it becomes really very straightforward. Great programming software, IMHO.
Note however that this only applies to Motorola systems (with a 3600bps control channel) that are rebanded. It does not apply to P25 systems. P25 systems should be left in P25 Auto mode.
