Just a thought about getting anything battery operated: If possible, maybe get them so that all your gear works on the same batteries. I know that some can't, but if your radio, flashlight, etc all work on AAs, you don't have to keep different types.
Our GPS system works on AAs and so do our strobes. That way, if the GPS goes TU, we can use the batts from the strobe, for example.
Important radio frequencies:
121.50: This is the international aeronautical emergency frequency
138.225: This is the prime disaster relief operations channel used by the Federal Emergency Management Agency; it is active during earthquakes, hurricanes, floods, and other catastrophic events.
154.28: Used for inter-department emergency communications by local fire departments; 154.265 and 154.295 also used.
155.160: Used for inter-department emergency communications by local and state agencies during search and rescue operations.
155.475: Used for inter-department emergency communications by local and state police forces.
156.75: This channel is used internationally for broadcasts of maritime weather alerts.
156.80: This is the international maritime distress, calling, and safety channel. All ships must monitor this frequency while at sea. It is also heavily used on rivers, lakes, etc.
