RTK fix availability?

Here is an image of my setup.

I ran the same test again. This time I logged the status of the RTK fix. After an operating period of about 2 hours an RTK fix was available for 76% of the time (one drop out that never recovered).

During this test both base and rover were stationary and there was a clear view of the sky.

When the RTK fix is lost I know from experience that a restart will resolve the issue within a few minutes. But if left unattended the unit is unlikely to recover by itself.

I’ve also observed that changing settings can trigger an event that recovers the RTK fix status. It almost seems irrelevant which settings are changed. The fact that a change has occurred matters more than the change itself. Is this to be expected?

If the log files are required I am happy to post them.
