Recently, I have been getting into amateur radio (ham radio) and have been learning about the different methods of transmitting data using these radios. One of these methods is called D-STAR. D-STAR allows the transfer of files and other data. Most importantly, however, is that it can be used for accessing the internet. For speeds of about dial-up, a person who has their amateur radio licence can get the internet out in the middle of nowhere with out any cell phone signal.
However, this D-STAR has some major issues. Mostly these issues are caused by the restrictions placed on transmissions sent over amateur radio. One of these restrictions is the prohibition of the transfer of ads. The FCC has made it quite clear that they do not approve of ads on amateur radio frequencies. This severally limits the sites that one can access over a D-STAR system. The other restriction that is placed on the amateur frequencies is the prohibition on encrypted messages. This means no SSL/TLS encrypted websites, no VPNs, no SSH, or any other form of encrypted data transfer. All data must be transmitted in plain text over a publicly documented medium. Security wise, this is a nightmare.
Personally, I understand the reason that the FCC has put these restrictions on. Amateur radio is ment to be for everyone to use equally and to be shared equally. If someone was to start using this privilege for what ever they wanted to, the frequencies would be completely filled up and there would be no useful transfer of information.
