Unfortunately i don't have any radios that uses digital encryption. And since i have several radios, i have been speculating on alternative methods. Her is one of them. On the picture you can see a mini PC, running HamScope (free software). The software can receive and send text using audio.In fact by typing text in one laptop and having another PC 3 feet's away receiving. It's best to use a cable between the radio and the PC, however i have mange to send messages by just holding the handheld in front of the PC, to another PC 12 miles away (70 cm). (picture)
By using this method you can send text messages using what you have. It's a process that takes some time and it's more suited between stationary stations. The mode that worked best for me was MFSK16. Just using a mode like that where the signal sounds like aliens talking, would deterrent 99% of any listener. However i would suggest using some for of encryption, most software programs will do. You can also do it manually but the code most be stronger than a simple substitution code.
If you have any other ideas to a smart and easy way for secure and simple communication please let us hear!
