    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:

Any way to lower error?

Is there any way to lower the error on an APCO-25 system. I have a BCD996T. I am getting a strong signal but occasionally the audio sounds garbled. I put the display on the screen for setting the decode threshold and noticed that when I get bad audio there is a large amount of error. If someone could explain the decode threshold detail in better detail I would appreciate it. My levels are 1.41 to 1.84.

If you enter the level menu by pressing the "Funct" button and the "Vol" button you will see the level of the p25 system. Press "Hold" on an active channel and note the lower value that the signal goes down to. eg 1.43. It should level out and the error level should go closer to zero or at least into single figures.
You can then turn the "Funct" button left or right which will raise or lower the auto starting threshold. I have found that setting this just above the lower signal level works best. eg if my signals level out at 1.44 I set the level to 1.45. It will keep this level until you re-download systems to the scanner. I have noticed that the scanner finds the level easier if it is set higher rather then lower then the final setting that it hits.
I went through and noted the best levels for each system I had programmed and set these in the system settings using the software in the "P25 Threshold Level". Now when I reload the systems to the scanner the best auto starting settings get loaded also.

Cheers
