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.
If you've been in an accident or have suffered a major medical event that leaves you incapacitated, one of the first things that first responders will check is your phone for medical information or an emergency contact. Modern smartphones have created standards for this, and have made it easy for users to put in their information so that first responders have easy access to it. Here's how to put in your information on iPhone and Android phones:
Bob would like to create a master drive that he can put in a safe deposit box that has all his private information on it. Leo says that's a good idea, but he doesn't really have to go to that extreme. One option is Google Docs, which would be sharable to his attorney.
If you're ever involved in an accident or have a medical emergency, your smartphone can play a critical role. But when it's locked, the information isn't accessible for emergency personnel to retrieve. That's where "ICE," or "In Case of Emergency" standards come in. You can set up your phone so that it will remain secure, while still making it possible for first responders to get to the critical information they need.
