WSJT-X v1.7

One thing to be aware of with WSJT v1.7 is the TX watchdog timer. I was on 10m JT65 and was wondering why the "TX enable" kept going off. Then the penny dropped. There is a TX watchdog  timer which by default is set to a number of minutes. If beaconing, this has to be set to "never" so the TX continues. Since adjusting this, I have had no further problems on JT65.
