I must have a different problem. I loaded Sentinal and the scanner scrolls thru like it supposed to do, but it does not lock on any of the frequencies. I have a silent scanning scanner.☹
Are you using just location and the full database? Or scanning a Favorites list? If location, verify that the location entered in the scanner is correct.
If using, instead, a Favorites list, post a copy of your file so that someone can take a look and make a recommendation on what needs to be added or changed.
Use Sentinel to "read from scanner" if you have made changes on the scanner that were not also made in Sentinel. If nothing was changed only on the scanner, proceed to the next step.
Click on the drop-down File menu.
Select export the Favorites list(s) into an *.hpe file.
Sentinel will ask you to select the list to export, and then you can choose whether to export all of the systems, or select only the ones to include.
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. To attach your list to a post, <right><click> on the *.hpe file and then chose
Send
From the menu that pops up next, send it a (compressed) folder. You can attach the zipped file.
Be sure that you do not have the squelch too tight. Setting the squelch to
2 or maybe 3 is usually sufficient.
Also check the service types that are enabled. When the scanner is shipped, and also when Sentinel is first installed, only Dispatch service types for public safety are enabled: Law Dispatch, Fire Dispatch, etc. Also turn on the Tac and Talk service types for them: Law Talk, Fire Tac, EMS Tac, etc.
