Hi Dave,
Started a flight from EGCC to KJFK in FS2020,got everything upto reaching FL360 and PF3 went silent on me,what i mean here is i didn't get Oceanic clearence and ny comms was on 123.55 i believe.
Checked comms for a waypoint 5620N and it wasn't set to correct freq and PF3 still remained silent.
PF3 is set to auto tune..if i have missed something let me know.
PS ignore bottom of log for hotkeys detected as i was pressing to see if i got any response.
Regards Dave
