Hello Leif
Thank you for the info and help. I have installed and run Zadig and updated the driver to WinUSB.
After this, Linrad still does not recognise the RSP2.
SDRUNO did no longer find the RSP2 with the WinUSB driver installed.
I am running Windows 7 Pro on a Lenovo T430 for info.
Do I need to place any file in the DLL folder after the driver update? - I do not think so. Perhaps, RSP2 is just not supported by this driver.
I will try Linrad with the build in AD in my TS590s. I also have an EMU0204/G11 SDR and VAC to experiment with.
I want to do some noise figure measurements with various power supplies, ferrites chokes, grounding straps in my shack.
