Mission 6 dodge 02 doesnt join

[Tomtom]

The first time i started the mission dodge 02 and his wingman joined and i could contact echo1...but i failed later in the mission.
Since the 2nd try i cannot contact dodge 02 and echo 1-3.
Frequences should be o.k.:
32,4

144,4

and 255,5 for the overlord

Anybody can help me?

Only my wingman answers and goes formation.

Finished the mission. Was a problem with a missing trigger at the runway.
