A two-way radio allows you to communicate with others over a set distance. For emergency prep, HAM radios are the best option.They are reliable and even handheld options can transmit upto 50miles.
One of my favorite things to do is talk with other ham radio operators through satellites or the International Space Station (ISS). To do this, I stand on a rooftop and tune a handheld multiband radio while tracing the orbit of a satellite or the ISS with my homemade yagi antenna.
The militia-patriot movement in America has embraced radio communications in a big way. Within the past decade, the methods and communications gear have evolved from basic CB or FRS radios, to now …
Baofeng just launched the UV-50X3 triband mobile radio and it looks like a jab, cross and left hook to the established japanese manufacturers who were caught dreaming about DMR, C4FM, D-STAR and other leprechauns. Yes, the chinese manufacturers aren't creative, but they are really good at copying stuff and
Diana Eng runs through the basics of how to set up a traditional HF amateur ham radio station at home.
In light of our next face-to-face meetup, Ham Radio 101, this article from HackADay gives a great overview of the current state of amateur radio and how it might be used by truckers and other mobil…

This is information about loop construction process from different amateurs using AAA-1 kit or LZ1AQ loop amplifier.
My favorite ham activity is making contacts via satellites. Not only is there the romantic notion of sending messages into outer space, but you have to
Learn why Amateur Radio Services (ham radio) is the most reliable emergency communications system, reasons to become a ham operator, and how to get started.

There's a lot of HAM radio forums out there. We've compiled a complete list of HAM radio forums for you here to browse, as well as our thoughts on each.
As you’re probably aware, communications right before, during and after a disaster will be critical to getting out o dodge, finding family members, or helping others stay alive. With the Internet, cell-phone towers and potentially even satellites being down, you may have to rely on HAM radio and other two-way radio services to send and ... Read more
Haunted as many others by radio interference and noise I started looking for a wideband portable antenna . Soon I became focused on a ...
A mast decoupling stub and other mechanical improvements mitigate structure effects and realize a mast mountable j-pole antenna.
