Hello, guys. Please, does someone know if these two RTL devices (R820T2 and RTL2838U) work fine with Gnuradio? Which is better? Thanks a lot. Cheers, Antony ---

these are two chips of the same device (RF front end and ADC to USB converter) and yes, they do work well with the osmosdr source of gnuradio.

Thanks, Jean. Do you know another SDR/USRP device with a receiver pin and that works well with Gnuradio? Cheers, Antony
