First check what the bandplan have set for a channel step size, that cannot be 6,25KHz. It has to be at least a 12,5KHz channel space so that will then double the scan speed. If not already done you create conventional channel banks with individual channels that are set to receive both analog and digital modes by setting each channels Audio Option to Search. In Sentinel when you want to change something like Audio Option you first change the setting to the one you want and right click on it and Copy. Then you click on the first line of that column, then have to cancel the popup window, and mark the last line holding down shift, and again have to cancel the popup window, and then right click in the column and Paste the value and it will change all lines.
For each channel you set something like a negative 5 sec delay and you set to record everything to the SD card. Let it scan for a full day. Easiest way are to then use Universal Scanner Audio Player and dump all recording to it and let it present the result and sort in frequency order. You will then see if it has recorded any digital system types to any frequencies and what type it is. You can then edit in Sentinel what digital channels of the wrong type to avoid and which to still scan to evaluate more by setting a -10 sec delay or a positive delay to those that isn't a continuos control channel, or find even more hits from frequencies that wasn't discovered during the first run.
