• Military use of shortwave is also common, but nearly all transmissions are encrypted, with voice encrypted using modes such as ANDVT . Data transmission may make use of encrypted RTTY, use Link-11 for radar tracking data, or use of Automatic link establishment modes to set up communication links automatically.
