EDACS systems use a little beep-beep kind of signal at the end of every transmission, if your scanner is programmed correctly, you will not hear it. As for the delay being set, ID Delay -- Yes; Frequency Delay -- No. Obviously if you are listening to a conversation on a specific TG ID, then you want to follow it. In nearly 100% of the cases, the conversation will move to a different LCN as the conversation progresses, so ID delay is good (the same can be said for Moto too.) If your scanner is programmed correctly, it will go back to the CC before that beep-beep I mentioned and look for the announcement of where conversation moved and go to that LCN. If there is no ID Delay, it will just scan into the next conversation if finds, may be the one you were listening to, or it may be another one.
