I am posting this here because although this isn't a cell phone forum, since this uses a smartphone and has the ability to send GPS coordinates, this might be of some interest to some members here.
I just heard about the GoTenna this yesterday. Unless I am way off base here, it sounds like they are using MURS frequencies for this. The application that would most interest me would be aboard a cruise ship when we go to the Caribbean. We have gotten by fine in the past with Nextel Direct Talk, but my wife and oldest son are so into texting that this might work for them. Somewhere I read on their website that they tried 900 mHz, but it wasn't successful for them. That sort of surprises me. In fact, I would think that 1 watt on the ISM 902-928 mHz band would have been quite suitable.
