LCN = Logical Channel number - tied to a frequency
LSN = Logical Slot Number - tied to a timeslot (pretty specific to DMR, since DMR is TDMA, two timeslots, two voicepaths)
You only need to pay attention to "LCN" in the DB for DMR if you are programming a scanner. Don't pay attention to LSN.
You only need to pay attention to LSN in the DB if you are using the DB to set up DSDPlus.
Thank You!!!
