content: Cheap and simple 100% secure global communications system. Cannot be tracked. A short wave radio and a laptop can be used in conjunction to create a very powerful and secure global communications tool. Write your text. Encrypt it .  There's many ways to cipher and encrypt text. Which method you use is your choice. But once you've done so, you can transmit this data over an unused short wave radio frequency anywhere in the world through burst transmissions. A short wave signal cannot be traced either, so the senders location is always secure. All you need to do is connect an audio out cord to a laptop with audio-in to receive data, or even a microphone on the laptop in range of the speaker of the receiving short wave radio. Data can be transmitted through audio. The SW radio signal could also be encrypted. So now you're sending encrypted data through an encrypted signal ( dual encryption). Two people with laptops and shortwave radios could securely communicate In real time anywhere in the world, and without internet. Emails and data can be sent this way without internet. Its a very effective and inexpensive system. Btw, break my code if you think you're smart.  R: 37 G: 138 B: 152
