Hi all,
I am an amateur radio astronomy enthusiast and I've been using an RTL-SDR (R820T) USB dongle for my projects; up until now I had been using a Windows 8.1 laptop, but that one is on the blink right now so I've switched to a Windows 10 computer. I've tried to plug in my SDR and run the flowgraph (attached), but I keep getting the output below: Generating: 'C:\\Users\\Deana White\\Documents\\top_block.py' Executing: C:\Program Files\GNURadio-3.7\gr-python27\python.exe -u C:\Users\Deana White\Documents\top_block.py Win32; Microsoft Visual C++ version 14.0; Boost_106000; UHD_003.010.001.001-0-unknown gr-osmosdr c653754d (0.1.5git) gnuradio 3.7.11.1 built-in source types: file osmosdr fcd rtl rtl_tcp uhd hackrf bladerf airspy redpitaya Using device #0 Generic RTL2832U OEM usb_open error -12 FATAL: Failed to open rtlsdr device. Trying to fill up 1 missing channel(s) with null source(s). This is being done to prevent the application from crashing due to gnuradio bug #528. gr::pagesize: no info; setting pagesize = 4096 I've run zadig for the RTL-SDR, and it works just fine with SDR#. Do you have any advice as to why I might be having this problem with the GNURadio flowgraph? Thanks very much! Have a great evening and take care, Ellie
