• 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:

Anyone have any idea what frequencies CBI formerly used on VHF and what type of encryption they used?

I picked up an old Motorola EXPO with securenet on ebay and it obviously was retired from this agency.

Believe that's illegal programming but I won't go there.

I don't remember Expos having an encryption option, but that was a lot of years ago. CBI was licensed for 155.460, but I suspect they also had some of the other CSP freqs for using where CSP didn't.
It used to be (and probably still is, though I haven't read the rules in a while) that for surveillance operations an LE agency that otherwise has a license could operate on any of the PP frequencies at less than a watt (or something like that) without a specific license. That was back in the VHF/UHF days. It was mostly to allow for body mics, but some small handhelds were also used that way. Don't have any direct knowledge of how CBI operated, but that was typical for a lot of LE agencies in the 80's and early 90s.
