Not working communication option F10 after air to air refueling

[fyodor80]

In part 2 after air to air refueling mission part 1, it is not working F10 option communication. Absolutely, I checked setting '\' for communication option and F10, but it's out of commission. So I cannot use communication function with JTAC. How can I do that?
