• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

How does one match up an ID in the format of 1810 with one in the format of 14-022? Why are different formats used (especially in databases)?

1810 is the decimal version of the Uniden AFS (agency/fleet/subfleet) listing.
Since there are 2048 possible talkgroups (16 agencies * 16 fleets * 8 subfleets)
you can work it out mathematically.

ie:
1810 / 2048 = .8837890625

16 * .8837890625 = 14.140625 [Agency 14]
16 * .140625 = 2.25 [Fleet 02]
8 * .25 = 2 [Subfleet 2]

That's how we get 14-022 as the talkgroup in AFS mode!

Thanks Charlie....For the explanation. It would be good if one format would be used in the various databases...just would make things easier.
