You can talk to satellites over lora with a 5w transceiver (source: done it), which is on the order of magnitude of a cell phone transceiver. Opus goes down to .75kbps. Ham boomerisms don't cleanly apply to modern voice codecs and digital modulation techniques.

- livueta 3y agoI used tinygs on a lilygo esp32-based board with a semtech sx1262. Before its untimely demise I used SDSAT, which would rebroadcast messages. I'm not currently aware of any active sats that do that, but you can receive telemetry from tons of them as listed on tinygs.
