We have developed new software for the Pi 3 and Gmc300S. The price on GMC300S has dropped tp $51 on Amazon, but the PI 3 kit is around $99. (Good news: The old PIs that we sold run fine with the new software).
The cost of the new software is $19.95 and the yearly membership is still only $19.95. Two sites with new software are running in Hot Springs and Conway Arkansas, on the map.
The reason we re-activate the Netc.com because of the threats for nuclear explosions around the world.
