• 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:

Update on TSA....

They are apparently using conventional talkgroups. I've got Unitrunker working quite nicely, as well as the CTCSS and MDC decoding utilities. kNACk decodes the NAC from Ohio MARCS voice channels quite nicely as well.

But, when monitoring the TSA (at the airport)... nada. I know they are using a different channel at each checkpoint so they do not have to listen to each other, so it must be different conventional talkgroups instead of different NAC.
