Even better, many of these repeaters are powered by solar or have built-in power backup. California Radio Interoperable System (CRIS) Project 25 Phase II. [citation needed], Stations that have antennas located in relatively high locations with views (from the antenna) clear to the horizon have a big advantage over other stations. The primary purpose is to provide secondary and backup communication to local first responders and disaster victims in the wake of downed primary infrastructure radio services (public service, cellular, electrical blackouts, etc..), ARES and RACES differ in one fundamental area: Structure vs. Outside of space adventures and emergency situations, we also use ham radio for: Of course, this list is by no means exhaustive. is coordinated and run by the US Federal Government activated among preexisting membership of amateur radio volunteers as part of disaster relief agencies implementation of disaster recovery. Its categorized in order of decreasing wavelength and increasing frequency to include radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma rays. QRV I remember the V in this as Vacation. The lower the frequency, the easier it is to transmit long distances with low power. Emergency Radio Frequencies Every Prepper Should Know I tried it with my Icom and all I got was complaints so I went back to standard, problem solved. Many radio's here in the USA are already narrow band but from experience I can say I traveled Europe last year and I monitored plenty of stations that were not using narrow bandwidth radio's. These 12 frequencies may not be used regularly in every location however they are available and very underused. 28.385 QRP SSB calling frequency It communicates that I have received what you have sent and asks if you have received what I have sent. Operating a ham radio that covers all frequencies or just hams in general, will require a license. Perhaps a great opportunity to learn about basic electronics!
