Hi,
Glad the setup went smoothly otherwise. The RTL-SDR V3 timeout is a known issue with some dongles that requires a short repair script to install the necessary drivers and kernel configuration. It takes about 5 minutes and requires running a couple of commands in a terminal window.
A couple of quick questions before I send you the details:
1. Are you comfortable opening a terminal on the unit and running a script from the command line?
2. Do you have another computer on the same network you could use to SSH into the unit, or would you prefer to work directly on the unit’s keyboard?
