Once it finds the LCN it gives you an option to save them

LCN FINDER LCN Finder helps you determine the correct LCN (Logical Channel Number) settings for those systems requiring LCN entry. You first need to create the system. Use any number as the LCN when you create the system, then run the LCN Finder by: MENU → Analyze → LCN Finder The scanner prompts for a trunked system. For LCN Finder to run, the system must currently be scannable (in an active Favorites List or Main Database and within the range set for scanning), and must be a type that requires LCN (EDACS, LTR, MotoTRBO, DMR TIII). Enter the first few letters of the system name, then press E to see a list of all matching systems. Scroll to the desired system, then press E. A list of scannable sites for the system is shown. Scroll to the desired site, then press E. LCN Finder mode starts. Once all LCNs are found, you can save the LCNs to the system. If you abort before all LCNs are found, you can still save the LCNs that were found up to that point. Note that LCN finder works best on systems with moderate activity. Too much traffic or too little traffic make LCN finder take longer to complete for most systems Steve
