[38;5;12mI recently pulled out my CB radio and installed it in my truck. This inspired me[39m
[38;5;12mto create an open source repository of all the radio related resources I found[39m
[38;5;12mhelpful and my notes on the subject.[39m

[38;5;12mThis project is aimed at hackers who enjoy all aspects of radio communication.[39m
[38;5;12mWhile a lot of this technology isn't usable by citizens and is heavily regulated[39m
[38;5;12mby the FCC, just knowing anything about it is special. I've been interested in[39m
[38;5;12mlearning the ins and outs of radio, as well as hearing stories, new and old.[39m

[38;2;255;187;0m[4mCB[0m

[38;5;12mCitizens band radio, or CB, is a two way radio spectrum dedicated to open use by[39m
[38;5;12manyone for almost any purpose. In the US and many other countries, it[39m
[38;5;12mdoes not require a license to operate. CB consists of 40 channels between 26.965[39m
[38;5;12mMHz and 27.405 MHz with channel 09 being dedicated to emergencies.[39m

[38;5;12mCB is more popular among truckers and radio enthusiasts, but its usefulness[39m
[38;5;12mdoes not stop there. It's great for long distance travel on popular trucking[39m
[38;5;12mroutes. You can tune to channel 19 (an unofficial trucker's channel) and get[39m
[38;5;12mreal time traffic updates, alternate routes and accident warnings.[39m

[38;5;12mGiven a good antenna that's properly tuned, a typical range to expect out of[39m
[38;5;12myour CB is about 2 - 5 miles (3.2 - 8 kilometers).[39m

[38;2;255;187;0m[4mGeneral Use[0m

[38;5;12mI've found a lot of my information on Jeep and trucker forums. From my own[39m
[38;5;12mexperience, it seems about half the CB transmission I hear include a handle of[39m
[38;5;12msome kind. I also hear a lot of swearing, so I wouldn't sweat accidentally[39m
[38;5;12mletting a "fuck" or a "shit" go.[39m

[38;5;12mCB is public. Very public. That seems like a "no shit" kind of thing, but with[39m
[38;5;12mthe current generation pretty much only using cell phones, it's easy to forget[39m
[38;5;12mthat using something as "primitive" as a CB radio is essentially [39m[38;5;14m[1mbroadcast to[0m
[38;5;12mthe world[39m[38;5;14m[1m (http://en.wikipedia.org/wiki/Citizens_band_radio#Working_skip).[0m

[38;5;12mTruckers tend to use channel 19. This is a good channel to monitor for traffic[39m
[38;5;12mconditions.[39m

[38;5;12mChannel 9 is for emergencies only. No general chatter on this channel. If you[39m
[38;5;12mare broke down, or your car catches fire, besides calling 911, this is a good[39m
[38;5;12mchannel to transmit on for help.[39m

[38;5;12mAround Portland, I hear a lot of chatter on channels 6, 17 and 28. These are[39m
[38;5;12mgood channels for entertaining conversation.[39m

[38;5;12mis a measurement of efficiency when connecting your antenna to your radio.[39m

[38;5;12mOptimum ratio is 1:1, although you'll probably end up with 1.3:1 or so. Anything[39m
[38;5;12mhigher than 2:1 should be considered a no-no since it can damage your radio and[39m

[38;5;12mThe hobby of Amateur Radio has a long and proud tradition. The very first radio[39m
[38;5;12mamateurs were true pioneers of radio technology. Amateurs 'invented' and refined[39m
[38;5;12mmuch of the early radio technology and were the first to transmit music, radio[39m
[38;5;12mplays, and information to the handful of people who had the new fangled radio[39m
[38;5;12mreceivers.[39m

[38;5;12mAfter World War II the hobby of amateur radio flourished. Radio clubs sprang up[39m
[38;5;12min schools all over the world and kids went home each night to build some new[39m
[38;5;12mcontraption, or have a chat with someone over the wireless. These young people[39m
[38;5;12mbecame the mainstay of the technical professions and developed much of the[39m
[38;5;12mmodern technology we use today.[39m
