That should do it. Be sure to use ID Search mode if you don't have any talkgroups loaded.

Assuming you have the NXDN upgrade and the latest Sentinel version, you should be able to create the system using Sentinel (and copy it to the radio) and/or directly via the radio keypad and menus - then run the LCN finder.

DMR and NXDN require ALL site frequencies -- just the control channel frequency won't work (unless it is the only site frequency). If you don't have all the site frequencies (or correct ones), it won't work...not well if at all.

LCN finder can time time - the busiest the system, the faster the results ... slower - well, you get it.

4/5 is pretty good and if that happened quickly, chances are, the 5 frequency is either wrong or not part of the system. What do you hear on that 5th frequency when programmed as conventional (if you look at the programming after storing the LCN finder results, one frequency should probably still have an LCN of 0).

You can monitor with 4/5 for a while and assuming it is a strong system and being received well, you should be able to determine (based on missed conversations/replies) if you have all the frequencies.

Also - with no TGs programmed (it seems), you'll want to run in "ID Search" vs. the default "ID Scan" mode.

You have to let LCN finder analyze that system, or have DSD+ do it for you.

After you get tired of analyzing you goto scan, not menu as that would erase what has been found (is that a bug?), and you can read the SDS100 using Sentinel to check what LCNs, if any, it has found. Or you can go into edit system and frequency and push enter on the scanner to see the LCNs found.

I found it easier to use a spare scanner or a SDR dongle and have DSD+ logging the systems control channel for a couple of days. But the LCNs found are usually not the same number as the scanner finds, you have to convert between their different ways of dictating logical channels.

Your photo suggests you are trying to scan something but doesn't indicate it is even receiving the system....

As Troy said.

RSSI = blank line and nothing on the S meter= NO SIGNAL

jodyobrien · Jun 20, 2018

NXDN.... Do you have that in your radio? did you install NXDN... nxdn may be in the DB, and load into the scanner, BUT wont work if there is NO NXDN in your radio...
