This is a situation where two different people can have two different approaches. Ultimately what works best is like beauty - its in the eye of the beholder.
If ABC is yakking all the time, then XYZ won't be scanned whether its in another Department/Group or in another Favorites List. ABC has to not be yakking for the scanner to move along to another Favorites List or Department/Group.
Yes there are fewer button presses involved with toggling Favorites Lists Quick Keys compared to Department Quick Keys.
While Priority scanning on trunked systems isn't like conventional priority scanning, (usually no pre-emption), setting Priority ID scanning so that the XYZ police talkgroups are "priority" that could help the matter some.
Not true.
Since the scanner will specifically check the system, only looking for xyz police, it will not be effected by the yacking of ABC police during this time slice of scanning.
If it's checking for xyz police at the same time it is checking for ABC police, which is always active, you will never hear xyz police.
You don't need to believe me, you can try it yourself. Once I found that it will catch more of the less active stuff on the system this way, (stuff i was missing), I specifically set up 5 different scanners this way, and hear a lot more other stuff on the system.
I don't do it with all scanners, but I am not interested in hearing the same stuff from all scanners.
