2017-03-27 Upgrading WSJT-X after hearing two words 7 months ago
Recently it seems radio noise levels on the HF bands have gone up again so I spend more time trying to make contacts in JT65 mode since that mode is more robust against noise than PSK31. To do this I use the WSJT-X software under Ubuntu Linux. WSJT-X is written by Joe Taylor KJ1T. The Ubuntu hams packages had WSJT-X 1.1 and I frequently ran across the problem that it crashes when the Internet connection to pskreporter is impossible when sending spots. In my setup the Internet connection drops regularly when I'm active with JT65 or PSK31 so that was an annoyance. Logged as Ubuntu bug #1673040: wsjtx crashes when internet connection is interrupted. But this weekend I was listening to Linux in the Ham Shack Episode #184 and in the presenters talking about re-installing a Linux system for amateur radio I heard two words: wsjtx ppa. As soon as possible I looked it up and found WSJTX General Availability Release PPA, followed the installation instructions and upgraded to WSJT-X 1.7. The main improvement is that it decodes better so I may make further contacts. Sofar it hasn't crashed on an interrupted Internet connection. I see one problem: it doesn't like talking to my radio via rigctld, giving an error. When I stop rigctld as started by Cqrlog and let WSJT-X control the radio directly via hamlib things work fine. And suddenly Cqrlog sees the QSO in progress and logs it when done.
