Before taxi Georgetown
- ATIS 118.6
- A recorded loop of the field's weather, active runway and any notices, updated hourly or whenever conditions change. Listen before your first call, and tell the controller which letter you have so they do not read it to you again.
- Clearance 119.125, 121.1 (WHEN GTU TWR CLSD)
- Clearance delivery issues your IFR clearance, and at busier fields your VFR departure instructions and squawk code. Call before you request taxi, with the ATIS letter and your intended direction of flight.
Taxi & takeoff Georgetown

Departure & arrival Austin

Also
- CTAF 120.225
