While somebody is celebrating, somebody is flying

I am trying to get some new experiences with PF3 flying to uncontrolled airports, but every time having problems with landings.
Not sure is this the problem with P3D, but when I reach last point and approach gives me last instruction it says contact Unicom at 0.0 Co pilot is in mode 2 and it should handle radios, but he does nothing. Obviously, it's not possible to tune to 0.0
So I was trying to contact somewhere manually.
When pressing key ` to open ATC window in P3D it gives me option "tune ESNG traffic on 122.9 and when I do that no hot keys are working.
But when checking map it shows other frequency for FSS in that airport and it's 122.1 same as I can find in PF3 Displayer.
Tuned to that, tried to announce position but it requested control centers frequency.
I've seen few topics about flying to uncontrolled airports, but could not find solution for my case.
Debug file attached, but ending is complete wrong, so I just landed and finished the flight.
