• 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:

A lot of these are already in the database:

42775 digital announce
DEC HEX Mode Alpha Tag Description Tag
42768 a71 A TCFD Disp Fire Dispatch Fire

Your talkgroup of 42775 is really 42768 + a Status Bit of 7 (multiselect)

Read Wise's thread for an explanation of why they're the same.

With that in mind, how can we tell if a TG that is already in the database is actually in the correct format or not?

All talkgroups in the database for a Motorola 3600baud Type II trunking system should be divisible by 16. In fact, if you try and enter anything not divisible by 16, the database rejects it.

Here's how to compare what you've found with your scanner with the database:

Take what your scanner gives you and divide by 16.

If it divides evenly, you've got the base talkgroup and you can check the database for that talkgroup.

If it doesn't divide evenly, take the whole number (number to the left of the decimal point) and multiply by 16. That will give you the base talkgroup that you can compare to the database.

If you're curious as to what the status bit is, multiply the number to the right of the decimal point by 16. You can compare the number with the table in the Wiki.

For example, if you see a talkgroup number of 35. Dividing by 16 gives you 2.1875.

Multiplying 16 by 2 gives you a base talkgroup of 32. You would check the database for a talkgroup of 32.

Multiplying .1875 by 16 gives you 3 which is the indication that the talkgroup is currently patched.

To sum up, you've found talkgroup 32 which is currently patched.
