My longest distance FreeDV RADEV1 contact 14,342km

There have been reports recently of 20m openings so I left WSPR receiving and noticed the US was coming in. Switched over to FreeDV RADEV1 using my macOS version of the software called FreeDVNeo. Keyed down and on Reporter I could see that Dudley WA5QPZ in Austin Texas was receiving me. Not perfect copy, but not bad either.


Also, I'm running the release candidate of macOS 27 Golden Gate which will be out in a few days. So far it seems stable and fast.

Hi Peter. That's certainly FB! Coming back to FDV after eight years, looks like a lot has changed. I'm guessing Codec2 is no longer used?

I saw a station using codec2 just yesterday. They were using the EzDV embedded hardware. (We haven't been able to fit RADE into an embedded device yet due to the memory required for the FARGAN ML model).
RADE sounds vastly better than codec2 so unsurprisingly people choose it if they can run it.
