RPi - Piaware SD card - NO mlat - Local clock source is unstable

I am running a Raspberry Pi B which after a few hours shows “local clock source is unstable” on the Piaware status page. After a reboot MLAT returns and is ok for a few hours, any suggestions what might be causing this?


Some ideas in this thread.

thanks, will have a read.
