I tried all the functions of the INDI RTL-SDR driver on the driver because I wanted to observe the radio waves, but there were many places where it did not work.
・ Raspberry-Pi4 4GB Buster (latest for both OS and INDI)
・ RTL-SDR.COM module V3 (latest)
・Even if the import location of the FITS image is changed, it is not reflected.
・ FITS viewer does not open even if I get a FITS image
・ Streaming mode does not work
・INDI Web Manager does not show drivers
・Crash when activating an item on the Signal Processing tab.
The log at the time of the above operation check is also attached.
