jodle 1 Posted November 26, 2019 When I set in FMC transponder code (via radio btn) it doesn't send that code into other systems like EFB (aivlasoft), Vatsim/IVAO etc. Only works set from knob on Radio tuning units. Share this post Link to post Share on other sites
Hans Hartmann 2323 Posted November 26, 2019 I just tested this and entering a transponder code into the FMS correctly sets the P3D variable. The software you mention should be able to get it from there. Share this post Link to post Share on other sites
Hoffie3000 60 Posted November 27, 2019 Just tested with VATSIM (via vPilot) and both variants works like it should. I´m shure you know the Squawk letters are from 0-7. No 8 and 9. Wolfgang Share this post Link to post Share on other sites
Hans Hartmann 2323 Posted November 27, 2019 Is it possible that you had the transponder on standby? Make sure it's set to Auto or it won't send anything. Share this post Link to post Share on other sites
