Decoding

Intro There's something slightly absurd about turning a tiny retro handheld into both an app development platform and a weak-signal radio decoder. The R36S - cheap, hackable, and rough around the edges - wasn't built for any of this. That's exactly why it works. The Constraint Advantage Modern development hides inefficiency. The R36S exposes it. With limited CPU, RAM, and screen space, you're forced to: Write tighter code Design simpler interfaces Think in constraints, not abstractions That same constraint-driven thinking applies perfectly to signal processing tasks like FT8. ...

WSJT-X 3.x has inbuilt support for band hopping! Results RX results from an experimental version of DDX: This is super useful for monitoring FT8 traffic on multiple bands. References libmirisdr-5 WSJT-X Improved

Here is the FT8 WAV test file. On an AMD64 machine: 1 second using the fast decode settings. We were able to get the MSHV's FT8 engine to work on Android, thanks to the work done by https://github.com/sannysanoff/SDRPlusPlusBrown folks. Around ~4.5 seconds to decode the same file. This is why we can't really have full-blown realtime FT8 decoder(s) on Android just yet! Idea: But we can surely use this full-blown FT8 decoder in our FT8 Decoder app which has no realtime requirements! ...
