Re: Tablet for SDR

I've used a Surface Pro 2 (circa 2015) for rtl-sdr applications, and it's really worked well. I don't foresee any problems with the newer surface tablets, especially if you stick to an i5 or better processor.

hydra_receiver.py and hydra_signal_processor.py along with the C files you havr to compile the first time you pull the source code are really the core components of the program. hydra_main_window.py is sort of the glue that holds it all together and is what hosts the GUI.
