Great Program !!!   I am writing a RPi program to control my rotor. I can get the azimuth from GT via the UDP  at port 12000 from "Aim Rotor". I want to display the call as well as the azimuth.  Is there a UDP that contains the call I just righ- clicked on ??  Where can I get that call from?   THANKS and have GREAT DAY  Jim, W8MRR
