- One-way voice link
-
A one-way voice link (OWVL) is a shortwave radio communication method used by spy networks to communicate with agents in the field. This system often employs recorders to transmit pre-recorded messages in real time or in 'burst transmissions,' which minimize the time that a spy needs to be 'on the air.'
This transmission method was also used during the Falklands War by UK elite forces to provide information about suitable troop landing areas.
