I currently have a working 1090 RB 'green' 1090 Flightstick on a RPi. Can I add the 978 'red' RB Flightstick to my existing Pi or do I need to obtain another? If I use the existing Pi, do I simply follow the 'GUIDE TO INSTALL UAT 978 MHZ ADS-B FLIGHTSTICK' and disconnect the existing 1090 Flightstick while installing the 978? Will both ADS-B and UAT then be fed to my existing feed after reboot? Thanks for the help.
