Rod KM6SN found that WSJT-X running on some versions of Linux would not work well with the µBITX. The problem was the Hamlib FT-817 protocol was not successfully connecting to the uBITX at startup.
For the past two weeks Rod has been working with Bill Somerville, G4WJS (developer of Hamlib) on the issues. He explained the nature of the problem, and provided CAT link protocol logic analyzer traces, and did bench testing of new Hamlib code Bill provided.
Bill took a lot of time out of his schedule to work on this, and it has borne fruit, having now identified the area that needed changes, provided modified software, and stayed with the problem through quite a few iterations of testing.
Rod and the rest of the digital mode enthusiast community will no doubt be grateful for Bill’s persistence.
The Hamlib FT-817 protocol has been modified to resolve the problem, and there should be an official WSJT-X release for Linux including this patch soon.
Details will be posted on uBITx.net when the new WSJT-X version is available.
