Are you locking onto the beacon and treating it like you were approaching a station (i.e. once your time to beacon approaches 6 seconds, put power into middle of blue and then wait for the signal that you're ready to drop)? If so, it should put you a lot closer than 500km. If you're doing all that right and still dropping out so far away, the easiest thing to do is SC over to the beacon. Shouldn't take too long, as 500km is not that far. If none of this helps, post some more specifics about what you're doing and we'll sort it out. Regards
