Does the 325P2 have a DND (do not disturb) Priority setting? If so, its the next best thing to the basic Priority setting that causes the scanner to jump to a priority channel every so many seconds, even while the scanner is stopped, listening to a busy channel. With DND the scanner will only check the priority channel(s) when there is no other activity. You may miss something on your priority channels while the scanner is sitting on a busy channel but at least it gets rid of the “popping” back and fourth between a busy channel and the priority chsnnel(s) you have activated.
