Hi Bob.

Looking at WSJT-X Improved here, at the top right of the Radio tab in
the Settings dialog I see a spin box titled Poll Interval.  Have you
tried increasing that value?

I use a K3 and just fired up WSJT-X after not doing so for several
months mostly to check antennas for the upcoming KS QSO Party so it was
easy to take a look.

Though I'm running Debian 13 here, the Radio dialog should be the same.
