Go and check if the right frequency is really active (via the flight plan information menu)  . If not just run the cockpit preparation checklist via PRO ATC X . After the checklist is done you should be able to request your clearance .

Having flown this with PATCX last night I have the answer

When you start your flight in PATCX, you should have ATIS tuned and the next frequency in the standby radio (if you have copilot handling the radios).

I've noticed that if you use the "comms swap" button after you've listened to the ATIS, you get no reply (as you say). If you return back to the ATIS frequency, and then use the "frequency comms swap" keybind (I think the default keybind is the "X" key), the frequencies will swap in the radio pedestal and you can now request clearance.

This is a known issue with several other addons (where the VC comms swap button isn't detected), and this is the work around

Hope that helps

It's in Prepared under the tab: Options-Controls-Key Assignments-Radio-COM 1 radio (transmit).I'm using this letter "O" and it's working for me.
