Ham Radio

Loved by radio otaku, military otaku, spies, and the like.

Airchat

AirChat is a free open source program developed by the Anonymous hacking group to anonymously communicate with other people over the air waves. To be able to use it you will need a ham radio with the open source Fldigi modem controller connected to your laptop or desktop computer.

AirChat transmits data using a radio connection, there is no need for Internet infrastructure or mobile phone network coverage. Sending data over the air waves has been possible since the invention of radio, as the Morse code pulses over the airwaves proved. Amateur radio operators send each other data messages daily with just their radio equipment, the Anonymous collective is not devising any new technology, what they do is to add privacy and security to something that already existed.

AirChat encodes data inside air waves with Anonymous own Lulzpacket protocol handling integrity and encryption. Due that in some countries encrypted airwaves over specific frequencies are banned, you are given the choice of sending the data unencrypted to avoid breaking the law. Other legal considerations are that ham radio operators must be licensed to operate on amateur radio frequencies, that will put you on a government list but this is not necessary if you only plan on listening in.
