Yep. This is true of many of the new systems which are using more and more encryption. Can't confirm what you can't hear, therefore the channels/talk groups might as well not exist from a scanning standpoint. Have that problem with the new Greenwich system which lost a bunch of channels when the new P25P2 system replaced the old digital system last year. Now you just see random talk groups flash from time to time with no idea what they are, though there are a couple of ways to get some clue of what they are even though you never hear the voice traffic. First, most systems assign the talk group IDs systematically. For example, you might have talk groups 571xx for police, 572xx for fire, 573xx for public works, and so on. Second, if you track the radio IDs, it'll give you a clue as to who is using the channel. For example, on encrypted talk groups, you can still see the radio IDs that are using the talk group, so if you listen to the unencrypted channels enough and follow the radio IDs, you'll at least be able to figure out what department is using the encrypted channel.
