Amateur radio operators have access to frequencies that work over long distances, bringing ham enthusiasts together and helping out during emergencies. Whether it is a natural disaster or electrical outage, amateur radio operators enable communities to stay in touch when other methods can't. TWiT also has a show called "Ham Nation" that features hosts/guests discussing the importance of ham radio and providing tips for particular situations/hardware. Check it out to learn more about amateur radio.
Lou is from the Bahamas and he's looking for a way to stay connected after a natural disaster. Leo says Satellite Phones are a good option. They aren't cheap, but if he can rent them, he can stay connected when he needs it. But a more affordable thing to do is to become a ham radio operator. He can get a handheld device and become a part of the emergency action network. Then when he needs to make a call, have a ham route the radio through to a phone. That's both affordable and valuable when there's an emergency.
