• 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:

I found 2 new freq in my area, 935.5 and 937.5 both are NXDN96, I get a burst of 2 or 3 seconds of just data but have seen no voice frames, has anyone decoded NXDN96 before and gotten voice?

thanks

NexEdge systems will do location data by interfacing a GPS receiver to the radio. This could be what you are hearing. It's pretty popular for taxi and bus companies to do this, some public safety agencies do it also.

NexEdge will also do slow speed data for telemetry, as well as video, any one of these could be creating the data bursts you are hearing.
