Not sure if I'm doing something wrong but, when I call up any radio command other than to my wingman or the ground crew, nothing happens: no pilot voice; and no audible responses from ATC; JTAC; tanker; or AWACS.
Again, my pilot can communicate normally with wingman/flight and ground crew, and even with the supercarrier (not authorized to land). With other modules, including the A-10C, the radio commands work as they should.
Every now and then while getting on without full radio commands, the pilot will blurt out a radio command, such as "inbound..." as if it was caught in a pipeline or something. I've tried re-installing A-10C Tank Killer, and repairing DCS, but no joy.
