Ham radio. 300 baud packet over HF (thousands of miles) is still a thing, as are newer data modes such as PSK31 and the JT family. I'm actively working on 1200 baud projects over VHF FM now. Back in the day BBS was very much in. These days the same tech is more often used for telemetry, tracking etc (APRS). Now you can do it all in software, ref https://github.com/wb2osz/direwolf https://github.com/wb2osz/direwolf and friends.
- adrianN 9y agoHam radio doesn't allow for encrypted connections AFAIK, which makes it a lot less interesting to me.
- matt_wulfeck 9y agoWhy wouldn't it allow encryption? Can't anything that sends and receives packets be able to be encrypted?
- adrianN 9y agoNot if the law forbids encrypted connections over Ham frequencies :)
- matt_wulfeck 9y agoOh I see. A policy restriction and not technical.
- Zaak 9y agoThe restriction is because commercial activities are prohibited over amateur radio, and encrypted traffic would prevent that rule from being enforced. I believe there's an exception for controlling remote devices when you need to make sure some rando doesn't brick your pricy gear.
- Zaak 9y agoIs that a privacy issue or some other factor?
