If you are using proscan I would set ISICS to record all and I believe it will record channels you don't have programmed but don't quote me on that. I have come across ids like that and couldn't identify so you are not alone. If you can figure them out you can always submit them for addition or review.So I finally have a computer with two dongles and sdrtrunk running. Liking it a lot. One of the things I haven't figured out yet though is the "long" user ID numbers. Most user IDs are seven digits or less. Like Ida County dispatch is 4799992. Some are much shorter than that. Troopers (351 in this case) have unit IDs like 11351. But sometimes a unit ID (I think) comes up that seems to be for admin functions or something -- I've never heard them talking. But something like 16777213 - 8 digits - will show up. Anyone know what that is? Also, a few more strange numbers pop up. Not sure if they're similar to unit IDs or talkgroups -- but 49516. What's that? Comes up often. And 65535. Any clues?
