It lets go all the way to tower and when trying to change to ctr it changes back to 126.50 and this time unplugged the Logi radio stack

Hi, there is an option in msfs which assist you to if you are using the build in ATC. You have to disable if you are using p2a otherwise msfs will switch back again and again. 

If I'm right you can find it here:

Options/assistance options/piloting/ai radio communication (ATC) 

Check if this option is turned to OFF

Best regards

Thank you I hope it works, I was about to give up....

Here's a list of options you may want to turn off in MSFS:

Options -> Assistance->Piloting->AI Radio Communications (ATC) - OFF
Options -> Assistance->Navigation Aids->Route & Waypoints - OFF
Options -> Assistance->Navigation Aids->Taxi Ribbon = OFF
Options -> Assistance->Navigation Aids->Landing Path - OFF
Options -> Assistance->User Experience->ATC UI Panel Open at Start - OFF
Options -> Assistance->User Experience->Show Message Log in ATC Menu- OFF
Options -> Assistance->User Experience->ATC Voices - OFF

Dave, that was it!! Works great now. Thanks, If I missed that in documentation, my fault

I am using XPlane 12 and encountered this problem  (with ToLiss A346) -- couldn't tune radio, either manually or under P2ATC control, or switch between active and standby.

  I finally discovered that the setting "auto-tune recommended frequencies" was checked in XPlane 's native ATC menu (the page that displays nearby controllers and ATIS) , and seemed to be overriding the P2ATC and manual commands.  Unchecking this option seems to have corrected the problem.

Well well!  Thank you, this solved my radio freq. problem - would never of thought to look there for a solution. Cheers.
