@Mark_Phillips is spot on. The goal here is to eventually make something that can be sold for about $30 and still allow distributors and resellers to profit from making the product available in every nook and cranny of the world. Nokia did exactly this with their $20 candy bar phones of yesteryear. Of course, we need to provide a useful service for that $30 (or whatever the final version ends up costing). Working on the service is something that can happen pretty quickly after we sort out all of the hardware and manufacturing headaches.
@Robert At $100 all-in, this is not a product for the people we really want to serve. Most of our individual customers are hams and electronics hobbyists. It’s not possible to receive an RF signal–especially a microwave (12 GHz) signal with generic consumer products. Over the air tv uses completely different technology. Even the very cheap and common rtl-sdr, which is based on digital TV components, is unable to receive the signal without additional, not-cheap or common hardware. We know this because we are one of the few shops in the world that are still designing new products with these chips.
A Pi and antenna + app could not accomplish anything useful. Not everything can be solved in software.
