    The other problem is the ship signal they traced would have been frequency shifted by the same amount as the time dilation. They would have had to compensate for that to even detect the signal.

    It was 1 hour : 7 years I think. So about a factor of 60,000. So if a ping was once a second it would be once every 42 days. And if it was a 1MHz transmission it would be at about 17Hz.

    So they somehow realized the once a second 1MHz signal was now a every 42 day 17Hz signal at 1/60000 the power. But didn’t realize that there was time dilation involved.
