I just bought a 2nd FA Pro dongle (blue one), to use with a different antenna or as a spare.
I’ve been trying to compare the two dongles. To do so i unplug one from the cable going to the RPi, and attach the other one.
This appears to cause dump1090-fa to fail (or something). ‘Top’ shows that dump1090-fa goes from using 27% of CPU, down to 0.3% after switching dongles. So then i do ‘sudo shutdown -r now’ and after a couple minutes the CPU usage is back to normal and i’m getting signals.
Am i doing harm to the hardware or software by abruptly unplugging the dongle?
I want to make sure the newly-bought one performs as well as the 1st one i got two weeks ago. Any comments welcome.
