Re: Getting Started Guide Needed

Dougga, the link provided is the best info, but sounds like you are at a starting point to write that documentation as you compile answers to those questions!

Turning off spectrum display

As I read - and it makes sense to turn off 'Spectrum Display' in order to reduce CPU load - improve performance. How about the DOA graphing(not phase differential calculations, but the DOA graph display cannot be turned off?) - is there a performance hit for continual plotting of the DOA graph?

Re: Phase coherent IQ samples for a Windows program

Windows development - what's your goal?

Re: hydra_main_window.py is empty

Are you connected to a KerberosSDR? In order to test Driver installation - Have you opened a terminal and tested each of the radios? (test before starting program) At this stage we recommend first testing your four tuners with rtl_test. Open four terminal windows, or tabs, and in each window run "rt...

Re: hydra_main_window.py is empty

After installing KerberosSDR did you first run setup_init.sh ? It will chmod and assign execution to selected files.
