Repeater
The Repeater was a British fire control data receiver placed in control positions aloft and in the Gun Control Tower[2] which displayed the enemy's inclination, speed and range rate in use on the Dreyer Fire Control Table.[3]
These were likely used only in ships carrying Mark IV and Mark IV* and Mark V Dreyer tables, as these were the only ones featuring Electrical Dumaresqs with commutators in their unique centreworks to transmit enemy speed and inclination.[4]
The Dreyer Handbook alludes to a "rate transmitter on the Dreyer table"[5] providing the range rate signals, but none of its descriptions of the various tables allude to such a transmitter. They could have been bulkhead-mounted transmitters or one within electrical dumaresqs and their underslung range clocks.
