what is the timing for each tone?Stevie said:You are correct for the most part. For ordinary dispatches, the data is sent over the data system, then you hear the three tones, then the dispatch. For some dispatches when the data system isn't working they will send out tones over the voice radio (5/6 tone), then the three tones and the dispatch. For any call requiring the BC, they send the BC's tone, then the three tone alert, then the dispatch.
For normal day-to-day operation, you can't differentiate between stations being toned out.
