I think the USB SDR is bad .. seems like it's failing after it runs for a bit ,,, which is likely hardware gets hot and something starts doing unexpected things. while true; do sudo vcgencmd get_throttled; sleep 1; done running this seems to indicate that voltage is fine ,, throttled=0x50000 means not currently throttle but was a some point throttled=0x50005 means currently throttled I think at least reading Pi Raspbian documentation ...
Fingers crossed it seemed to fail when I opened the Dash board before or it might have been a coincidence
Dashboard uses some cpu to run ... so maybe ... if CPU ramped up that other power supply was giving it issues
I moved some MLAT servers around West EU, Central EU, East EU are now on a 5 Ghz server. I also figure out how the coverage map and sync table are created, so I can send that to @MDA.
