You need to clarify what you mean by "nothing displays".
Did you mean that you get a "nothing to scan" message, or that the scanner seems to be scanning, but nothing is being received.
Have you reviewed Service Types, so that all the Public Safety types are set as enabled? Not just DIspatch, but also Tac & Talk? (like Law Talk, Fire Tac, etc).
Are you using location control?
If so, have you entered your current location?
For your Favorites lists, did you create them manually, entering the frequencies & system details by hand, or did you append the systems from the database.
If you have any DMR or NXDN systems in your list(s), have you also purchased those upgrades?
Give a little more detail on your problem, so that we can help you figure out what's happening. You might also attach one of your Favorites lists to a post.
Attaching an *.hpe file to a post
Use Sentinel to "read from scanner" if you have made changes on the scanner that were not also made in Sentinel.
Then, export the resulting Favorites list(s) into an *.hpe file. Then, attach that to a post and upload so that we can take a peek & see if anything is out of place. The Export function is listed under the File drop-down menu. If you have more than one list, export each Favorites list separately.
Note: To upload an *.hpe file, to the Forums, you must change the file extension to one acceptable per forum requirements. To do that, note where your exported *.hpe file is saved on your PC.
Using Windows Explorer, find the file.
There are two ways to do this. You can either change the file extension itself, or compress the file using
7-Zip or another file utility. The *.zip file extension can be attached to a post and uploaded to the Forums.
Or, using Windows Explorer, rename your file one of these two ways:
For illustration, let's call your exported file '
MyFile.hpe' (without the quotes).
<Right><Click> on the file & choose Rename from the pop-up menu.
You can then rename your file to
MyFile.txt, or
MyFile.hpe.txt in order to attach it to a post. Whoever views the file will need to reset the file name back to
MyFile.hpe, then it can be imported into Sentinel for viewing.
