Figured out a few more things with RTL SDR, found out the physical dongle i had did not support it.
May not be too late to order one that does.
I still have yet to try the Blue Dongle though.
This project is consuming a lot of time but is fun.
Update: The Blue RTL SDR does do ADS-B aircraft monitoring
Update2: I also had a chance to install Linux on a brand new laptop. The interesting thing is that CentOS does install via UEFI on a secure boot system. MINT does not!!!
