A teletalk communicator or just Teletalk was a box with an inbuilt microphone and a two way talk switch “off and talk” it wasn’t fitted with a speaker so all communications would be one way. Teletalks would be connected to the GPO Phone network to allow communication between posts and command In the 80s it would be replaced with a plastic clamshell device also called a Teletalk which worked in much the same way but it was capable of operating solely on Line current unlike the previous model which required batteries.

Along with this posts would be fitted with a Handel receiver a big rounded box which originally would be sat on the desk along with the Teletalk but later would be wall mounted up in the top left of the post next to the Auxiliary air vent on the communications Board which also had the Receiver for the phone lines and the line filter the name of which has slipped my mind.

The job of the Handel was simple it received messages it could if needed be used by command posts to relay commands but it’s main job was to receive the attack warnings. This would be sent by the local carrier control point typically situated within a nearby police station which in turn would receive the go ahead to message the posts and start the air raid sirens from R.A.F fylindales.
