Hacker News – Via Shortwave Radio

This is a full length demonstration showing a 900km link beyond line of sight. Using robust narrowband data transport bouncing off the ionosphere to access the Hacker News website as well as pull an article across the link. The link is bidirectional and interactive.

Using 500hz bandwidth. Later in the demonstration the same data is pulled directly over the internet as a speed comparison, showing that the shortwave method is quite β€œusable”.

The background music is included as well to emphasize the robust nature of the data transfer, it may be possible to decode the information in spite of the QRM 😼
