I’m running a Pi for testing different antennas so loaded the Joe Prochazka web portal. I noticed the dips in CPU every 10 minutes so thought I’d forgotten something as I’ve never seen the dips before. I formatted the SD card and loaded 3.5.1 Piaware but the dips are still there.
The dip are genuine as I can see them on the message count on the map view.
Any ideas what is causing them?
