> CB radios Boy would I love to get ahold of some handheld radios designed for 'prepper' use. 1. use cognitive radio techniques to find and frequency-hop to whitespace radio frequencies that are conducive to best propagation over the 0-10 mile range on unlicensed radio bands 2. use ad hoc mesh networking to support sending datagrams like text messages (preferably E2EE via say Signal Protocol) or GPS coordinates up to, say, 7 hops away 3. support a 'emergency mode' where the radio power limits are relaxed and the frequencies for use by point A are relaxed to cover any radio band not actively reserved by law enforcement / military / first responders. In theory the cognitive radio techniques of frequency hopping and waiting to transmit until confirming radio dead air would prevent radio interference with whatever commercial TF / broadcast radio / CB radio / MURS/FRS/Business band radio signal, but to keep the FCC and HAMs hearts from stopping, things like the military bands could be blocked off just to provide that last 0.00001% guarantee of safety against interference. All of the 3 _seem_ possible to productize using SBCs and SDRs, but I don't know where to start, I think I gotta finish my 8-bit breadboard computer YT series by Ben Eater before I even tried to tinker with this.
