I got that email too...looks interesting. One thing I didn't see in the spec's is what wireless frequency the ISS uses or what distance it can be from the console receiver. Maybe that information is there and I missed it.
It seems like Ambient has 3 products WS-1002, WS-2902, WS-8478, that have a lot of overlap in features. It would be nice to see a comparison review on these three products.
Edit: I found the answers in the user manual ... 915 MHz, 300 ft line of sight, 100 ft. most conditions.
Also, I see there is no FARS, not even as an add-on. That seems like a significant shortcoming.
