I have recently sought to understand the correct LCNs to use for two area DMR Tier III systems. Ultimately, largely through trial and error and some detective work, I was successful. In *BOTH* cases, the LCN sets that ultimately worked best used values that were HALF the values listed in the RR database. The LCNs listed in the RR database did not work at all.

Wonder if anyone else has had similar experiences?

If the RR database used twice as high numbers for the LCN's then it could be LSN's that are one channel for each time slot that all radios use and the actual trunked system except Uniden scanners that use another method setting a channel number for each frequency and then monitor both slots to see which one that needs to be monitored. It then uses half of the LSN values as channel numbers.

It's like Uniden from the beginning where trying to not infringe on a DMR patent and did their own thing to avoid paying any licenses, but at the end they payed but still stayed with their own unique channel numbering LCN thing, maybe development already had gone too far.

RR database are a general database using the actual systems information but Uniden use that and convert LSN to their own LCN and use in their own database that can be imported using Sentinel.
