• 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:

Hey,

Does anybody know if there is a way to access the new trunking system for the Goucher College Public Safety frequency? They upgraded to a digital system over the summer on the same frequency and all there is is the diesel-engine-trunked-frequency-sound.

Any input/assistance would be greatly appreciated.

It sounds like it may be a proprietary protocol like Mototrbo which uses one frequency to create two digital voice slots. Not scan-able.

Just to make a slight correction...

MOTOTRBO is based on an open standard called DMR (Digital Mobile Radio). The 'over-the-air' protocol (a.k.a. CAI - Common Air Interface) is not proprietary. Conventional simplex and repeater systems are not proprietary. The trunking formats are proprietary.
