To adjust the volume of any system's sound please:
1. Open MSFS2004/Captain_Sim/130/sound.ini
2. Edit any Volume=XX line. XX=0-1.0 (0=mute 1.0 - maximum volume)

the TCAS audio messages are #56-61 in the .ini file.

------------------

C-130 does not use the FSUIPC at all.


------------------

Most of the TCAS problems described above are related to the power loss due to generators disconnection. Already fixed in SP1.

If you do have the power onboard but the TCAS still doesn't work, that 99% means you are not on Windows XP system. Search Technical Suport System for details.
