I have reloaded the PMDG 777 software twice now and get the same result.
The problem is:
In the radio stack, for instance, I tune into Heathrow tower live ATC in the active window, and 122.80 in the standby window.
I Get no response from Heathrow but if I switch 122.80 into the active window and Heathrow into the standby window, Heathrow responds.
Can any member please advise on a solution to this problem?
Thank you
Donald
