Once you hear a pass, then just remember that passes are 36 minutes earlier each day and the next pass on any given day is 98 minutes later (unless that was the last pass of the day). During a western trip, just jotting down the time of a pass heard, then I could predict pass times therest of the day and every day for weeks. Always just adding 98 minuets to the next pass and listening 36 minutes earlier each day.
