• 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:

This a copy and paste from Larry VanHorn's BTown monitoring blog. I think he answers the question of Pro-Voice very well, which I think JC uses.

"Monitoring the Pro Voice Digital Protocol - Not!
I have noticed some people using Google searching for information on how to monitor a radio trunk system that uses the ProVoice digital protocal.

In short, "you won't, and there will not be a scanner that will include that mode." M/A-COM has made it clear that they will NOT allow the scanner manufacturers a license to include that proprietary codec in a scanner. The IMBE vocoder is used in ProVoice, but ProVoice is not compatible with Project 25, so a Project 25 scanner will not automatically be able to follow ProVoice systems.

Oh yes, same thing applies for:

Open Skies, which is used by the Pennsylvania statewide public safety system uses the popular Internet Protocol (IP) and is rather unique in that all radio traffic is digital from one end of the system to the other. OpenSky uses a different DVSI vocoder known as AMBE (Advanced Multi-Band Excitation), and is not compatible with Project 25.

Aegis was originally developed by Ericsson (now M/A-COM) that uses yet another type of vocoder, and it is not compatible with Project 25.

Motorola VSELP is an older Motorola ASTRO digital protocol that uses a different vocoder referred to as VSELP, which stands for Vector Sum Excited Linear Prediction. As with any non-IMBE vocoder, VSELP is not compatible with Project 25.


And those are the facts folks.

Man there is a whole lot more monitoring in JC than just 154.340 and 155.235..Yes those are the main FD and Ems dispatches, but if you have a trunktracker scanner just program in the JC Edacs system.. You will then hear Selma, Smithfield, and most small town PDs in JC.. The only thing you cant hear is Sheriff Dept, most ops channels, Ems Disp, and Fire Disp.. But things can get exciting on the TGs you can hear.. You dont need to hear the JC sheriffs department to keep up on info in Johnston County.... Just do some research on the database...
