automatic connecting to ground when startup ' cold and dark'

[Bunckman 0]

Hello all,

I have a problem with changing the frequencies when I startup a plane 'cold and dark' in MS2020.
The frequency goes from ATIS to GROUND immediately after connection with MS2020!
This can no longer be changed, neither from the cockpit nor from Pilot2ATC.
In the CONFIG the Master Battery and Avionics switches are on

If I boot from the RUNWAY everything works correctly.

Does anyone know what could be going on here?
Do I have a setting wrong?

This is almost certainly because you have not turned off all the ATC assist options in MSFS, so MSFS is controlling your radio frequencies.

Thanks Dave!

you were absolutely right!

In MS2020 I had ' delegate ATC to AI' still checked. That was the problem.

Thanks again!
