There is a weird problem with VHF radio. It just stops working at some point on every mission

[DmitriKozlowsky]

I have it set to FF with manually entered freq. Usually for ATC. For some reason, on every mission, at random time, it simply stops working. No transmissios! The radio frequency flashes , but there is no transmission, and no reply. Not from ATC, not from wingmen.
