Not much more than is on the website, but I did post a blurb on it

from someone who was experimenting with the "black box" version, which
puts out NMEA sentences that can be used by applications like Maxsea
and Rosepoint Explorer. He said he hooked it up with a rubberduck
antenna on land, and was picking up ships a few miles away.

This unit he

is a similar device. Quite cheap at US$575 as this is a dual channel receiver
- can pick up channel A & B at the same time unlike the NASA unit which
requires you to pick one channel or the other.

I've been using this Chinese unit for a couple of months now - getting
signals out to 50 miles with no problems even though I'm 25 miles inland.
Sometimes get signals over 80 nautical miles.

Here is a link to some testing I did when I first got the unit:
