When the KSTJ tower is closed

The tower is staffed WED-THU 0800-0000, FRI-TUE 0800-1800, OT BY NOTAM. Outside those hours Rosecrans Memorial Airport has no operating control tower: it becomes a self announce field on 126.9, and separation from other traffic is yours, not a controller's. Report your position and intentions on entry and on each leg of the pattern.

Runway lighting is often pilot controlled once the tower closes — check the KSTJ airport page for the click sequence, and what to say on the radio.

Before taxi Saint Joseph

ATIS 125.05: 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.
ASOS/AWOS 125.05: An automated weather station reading the field conditions aloud — wind, visibility, ceiling, temperature and altimeter. It replaces ATIS at a field with no controller to record one. Get the altimeter setting before you descend below the transition altitude.

Taxi & takeoff Saint Joseph

Ground 121.9: Ground control owns every taxiway and inactive runway on the field. Call for taxi with your position and destination on the field. You need an explicit clearance to cross any runway, including one that is not in use.
Tower 126.9: Tower owns the active runways and the surrounding surface area. Call before entering the surface area inbound, and hold short until you are cleared to take off or to cross.

Departure & arrival St Joseph

App/Dep 120.35, 124.7: One radar controller working both arrivals and departures — normal at a smaller TRACON. The same frequency takes your climb out and your inbound call.

Also

CTAF 126.9: The common frequency pilots use to announce themselves to each other at a field with no operating control tower. Nobody is controlling traffic — you are self announcing. Report your position and intentions on entry and on each leg of the pattern, and listen well before you transmit.
UNICOM 122.95: A ground station run by the FBO rather than the FAA, for fuel, parking and airport services. Use it for services. Where the field has no separate CTAF, the same frequency doubles as the advisory frequency.
Emergency 121.5: 121.5 is the international emergency and distress frequency, monitored continuously. Declare on it if you are in trouble, and monitor it as a second radio when you have one free.
