It took forever to setup and there was no controllers in my area available from midnight to 11am. For some reason I couldn’t hear the controller and they couldn’t hear me so I used the text chat to request clearance delivery. Controller proceeded to ask if I’m /t or /r. I assumed it has something to do with him asking about my mic but I’m not sure what that is so I disconnected out of frustration. Maybe transmit/receive I guess? Idk what was he asking?
