    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:

What is this UHF Trasmission?

I know who the frequency belongs to and all the info on file for it, but I don't know what type of transmission it is or how I would decode it.
It sounds like some sort of telemetry chirp.
It's an FXO type station and is in the IG - Industrial/Business Pool, Conventional single unit with multiple locations and 2W max output.
The recording looks like each sound is unique and I didn't see any that were the same.

What type of transmission is this and how would I decode it?

1200 baud AFSK data.
Probably SCADA
There are a lot of different data transmission formats that could be used depending on what type of control system and radio modems they are using.

Yup it is SCADA. Decoding it probably won't tell you much. You will get the status on/off of various unknown devices and quantity values of unknown sensors. Somewhere in a control room, all that data is converted to English and Graphics on a screen and lighting bulbs on a tote board. Better to find out who the licensee is and ask for a tour of their control center. It would be a far more educational endeavor. I worked with the South Florida Water Management District as a contractor finding interference on their systems. It is pretty fascinating that all this data is collected from all over the Everglades and used to turn on huge pumps to counter Mother Nature.
