That's not what the pop-up tip on FreeScan says - Assaf quotes that function as allowing the 'priority' talkgroups to actually preempt other non-priority talkgroups on Motorola Type-II systems
I'll be honest - I've not used the feature since I don't have Mot systems in my area. I was simply basing it on
the Uniden user's manual:
EditSysOption < UnidenMan4 < TWiki
Choose On to have the scanner check any priority-labeled channels in this system during Priority ID Scan mode. Choose Off if you want the scanner to ignore this system when scanning priority channels.
===
...and then...
Priority Scan mode
At a specified interval, the scanner interrupts its current operation, checks the user-designated conventional priority channels, then resumes the previous operation. You can set the interval for priority scan checks.
If no conventional channels in enabled and unlocked systems are designated as priority, the scanner will display Priority Scan No Channel.
For trunked priority channels, you need to enable priority scanning in the system option menu as well as tagging the channel as priority. Trunked priority only works while scanning that system's control channel or (in the case of Motorola systems) when the scanner is scanning any channel in the system.
I have selected talkgroups labeled as priority on the statewide Motorola 3600 Baud system and they preempt other non-priority talkgroups.
Just so the OP doesn't get too confused - we're off his original topic
The feature does not work with EDACS.
So ZNR - to confirm - you are saying that the pre-empting only occurs if you have Priority ID Scan enabled? If it's disabled, then it doesn't preempt?
I'll make some Wiki edits if you two are certain about it.
