Much appreciated. You can use the lvar XMLVAR_Transponder_Mode with the following values: 0 - ALT RPTG OFF 1 - XPDR 2 - TA ONLY 3 - TA/RA 4 - STBY To assign to an lvar, you can either define your own preset, use a macro or add the lvar to an FSUIPC offset and use the offset controls to change the offset value and this update the lvar. For example, to use a preset, add the following to your myevents.txt file: //HorizonSim/787-9/Controls Horizon_787_Trannsponder_Mode#$Param (>L:XMLVAR_Transponder_Mode) and assign to that preset with a parameter of 4,0,1,2 or 3 for the various positions.
