When running discovery for a trunked system in my case Greater Cleveland Regional Radio Network in Cleveland Ohio when looking at the logs under audio type there are Digital and All. I can only hear the traffic on the Digital audio type and even though there are many of seconds logged on the All audio type it will not play back. Can someone explain. Maybe something I'm doing wrong in the setup of discovery?
Generally, the ones listed in All, that you're not seeing the option to play may be transmissions where no audio file was created.
Look at TGID 202 in the Discovery log viewer in Sentinel.. It shows 600 seconds (the max duration in a Discovery session) in Digital, with 15 in All.
Now, look at the folder via File Explorer (the new name for Windows Explorer in newer versions of Windows).
You see two folders for the same TGID. The
202_D contains the audio files, totaling 600 seconds, that you can play.
The
202_E folder is empty.
Those are usually transmissions so short that no audio is captured. If you were running a log in ProScan (or I presume ARC536, though I do not have that software), you probably would see a number of logs for zero seconds (unless you have ProScan set to not log entries less than 2 seconds). So, no audio file is created, but the 'count' shown for the
202_E folder should be the number of times that a key-up, but no audio, came up.
