There's a thread about it here somewhere. Surprised the website is still up.
I doubt it was a scam. There's even an April 2015 update. But the guy obviously was like some sort of gearhead here, but with no practical experience in the field, and obviously way outta his league. I was grimacing reading about the FCC stuff, since I thought it was harebrained to even think about including a radio (and I think it might have even been contemplated to put a 2M amateur radio in...sheesh). By now much of the tech is obsolete anyway. And now this:
The idea is simple, a basic unit with gps and environmental/locational sensors with a removable radio module. This would allow us to certify the module once and not worry about future design changes on our device. A detachable solar panel with second battery would allow for charging while the device is in use, also mitigating heat issues with the core system. Modules give users a choice in the features they need and/or want depending on the occasion. The modular port would support Earl’s walkie talkie, AM/SW/LW radio and anemometer. Trying to fit everything while keeping the device functional is challenging. We discussed similar solutions with Onyx in the past, but Netronix was proactive and suggested this solution from the start.
So now it's back to a tablet, a radio, a thermometer, and a solar panel. In "modules," which begs the question why you should just buy these separately as they'd be cheaper, more robust, most usuable, and more reliable. I dunno why anyone would find a mashup of these attractive. Although I guess $700K worth of folks did.
