DaveIN,sorry to sound dumb where would I find the manual and analize? I dont see it on the trunker screen if that is where you mean.
On the scanner You would find that.
You need to switch your channel to a control channel and _sit_on_it_ -- no, not Fonzi style... but the term applies.
Either go to Tune mode and enter the frequency in and then let it sit there and play the digital audio (you can turn the volume down) and let Unitrunker collect data, or Find the frequency already programmer in your scanner in the TSYS object - hit Manual, find an object associated with the system you want to monitor, then press TSYS (it's a softkey that'll show on the screen). Then press Analyze and scroll up and down through the system frequencies until you find the one that is the active control channel - Leave your scanner on that active CC and Unitrunker will collect data.
If you only have one scanner and you want to hear the audio, then Unitrunker is going to switch from the control channel to the audio channel when audio plays (at which time Unitrunker will lose the control channel) - Then it will resume listening to the CC and collecting data when voice traffic stops. This assumes you have it configured properly.
There are some instructions on the http://www.unitrunker.com
website if you look closely.
