If you are a radio operator, the idea of sending photos and data via voice channels is nothing new. Hammam has many techniques for this and – not so long ago – even most data transmissions were over telephone lines. Now, however, anyone can join the game thanks to the cheap availability of software-defined radio. Several shortwave resellers send encrypted data, including images and even entire web pages. You can learn more at Swradiogram website. You can also find step by step instructions.
WINB in Pennsylvania and WRMI in Florida have broadcasts that include scattered data. To play together, you will need a decoder like Floods or TIVAR. If you don’t have enough radios, you probably can borrow some from the internet.
At first glance, this may seem like a disgusting hobby, but we can’t help but think that in places where data is censored, radio can be a viable way to send information. Some referral codes for error correction and perhaps encryption could be a way to save data to those who are denied free access to the Internet. After all, the story is full of stories about secret radios tuned to the BBC or some other radio outlet, or examples of secret messages in shows, such as Swan Radio. If you know the Morse code, you may even get a warning about yours forthcoming rescue.
