In the new version 3.0 software for the TRX-1, I found a bug. Under "Trunked Radio Systems" on the "System/Site Options" tab, for NXDN Site Options, if you select a RAN greater than 15 from the drop down list, it reverts to a number less than 15 when you click off that site and then click back on that site. RAN numbers 15 or less don't seem to be affected.
