Search on \railworks folder for files named
*Cab_Radio.dav or
*Radio.wav and you'll find some (sometimes different) from other installed engines (usually on \Audio folders). Copy any from original Audio engine folder and paste it into the related Audio ES44AC engine folder. Rename it do match the same name of sound file you are replacing (starting with ES44AC, I guess).
At my side I deleted all radio chats of game, first because I don't understand almost nothing,

and second (even if I understood) because is very annoying hearing same thing hours and hours long, especially having nothing to do with the scenario you are playing.
For those bothered or annoyed with radio chats, I have created a bat file (which I named "Deleting RADIOS.bat") with these command lines inside (can be placed anywhere on your pc). Be ware that
my batch file deletes ALL (everyone) radio chats of game. For deleting especifics some radio sounds you can edit or create your own new command lines.
Cheers,
Doc.
