• 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:

Was using DSD+ and SDR#, found a P25 signal. DSD+ reports that it's encrypted. Would look at the FCC Database but I have no idea how to use it.

Frequency: 409.537
I'm also noticing other P25 signals but they appear to have unidentifiable NACs. Will post more if I find more out.

That frequency is in a range normally used by Federal agencies, and as such, it would not be listed in the FCC database.

Several of the military bases' trunked systems in the S.A. area have frequencies in that frequency range.
