GRT Avionics

I have an HXr with the Safe-Fly/uAvionics module and a GTX-330ES transponder. I am receiving traffic fine but the ownship is also displaying and creating a traffic alarm in the HXr inset. How do I filter that ownship data in the HXr?

I assume the 330ES is doing the transmitting? And the ownship is displaying your N-number, not just some anonymous target? You need to configure the Flight ID and Address in SET MENU, General Setup, Flight ID and Address. The Flight ID should be your N-number and the Address should be your Mode S address/code in hex format. This is the 6 character Mode S address/code on your aircraft registration (you can look it up on the FAA web site), and it normally starts with "A" for N-number aircraft. If you are using an echoUAT in app mode then you should enter the address and N-number into the echoUAT as well so all connected devices can identify the ownship.
