I tried to pick it up a couple of nights ago, it passed overhead about 5km out, so pretty much minimum distance.
I used a home brew quadrifilar helix antenna, ideal for overhead satellites with my silly expensive LNA in front of a SX1268, but I did not even get a pre-amble detect.
They are trying to use a lot of power to get a command to it, not sure how much, but I could manage 60W here …
