@Powernumpty Deleting the corresponding folder in wsprdaemon/signal_levels/ did the job for me.

Adding a plausibility check might be also a good idea. Moving 1000s of km in a second is an unlikely thing to happen.

I have device with a commercial GPS timing receiver. After powering it up it runs a discovery mode where it is determining the location. Once this is done, it is assumed that the position is stationary. Apparently this helps to get better timing precision.
