Hi, found this issue and managed to work around it so hopefully can help some others:

Repro Steps:

  1. Windows 11
  2. Run CMD as Admin
  3. Change Directory to bt_driver folder
  4. bias_tee_on

Result:

Workaround:
You can update your RTL_SDR V3 to always have the bias tee enabled.

I did this on a raspberry pi, but might work via Windows.

  1. Instructions: https://github.com/rtlsdrblog/rtl-sdr-blog
  2. Following doing this, moved the SDR v3 back into my Windows 11 PC.
  3. SDR# could not find the device, so I used Zadiq to replace the drivers again. Then it worked.
