Report preparation

  • I used the AI-assisted bug report tool (Help → Support → File an Issue)
  • I have attached a support bundle or log file

What happened?

I have noticed that WSJT DT timing drifts off, showing up after a few Transmit cycles, to the point that decodes stop. This seems to be with all latest builds of AetherSDR, from approx. v0.7.8.
This does not happen when using an IC-7300 on the same computer with WSJT and having AetherSDR running with WSJT, so CPU load was ruled out as a cause.
