You will need to make an update to your pilot or ATC client in order to use VATSIM from the launch date. Simple instructions have been written for you to follow: please read them carefully!Update My Client
Brand new codec simulating both VHF and HF radios, including optional realistic distortion, white noise and realistic VHF simulation.
An 80% reduction in latency, making busy frequencies more realistic and less frustrating.
Transceivers are set up as per real ATC positions, with signal strength decreasing with distance.
Cross coupling allows controllers to open multiple frequencies, and air to air comms between pilots works just like a real radio.
The VATSIM community is providing support for this change through our forums!
