Notes:

The ESD1753N is the Manual controller option from the ESD1741 lightweight V.H.F. military airborne transceiver. The system is designed to provide high-reliability air-to-air and air-to-ground communications in all types of helicopter and fixed wing aircraft and is intended primarily for air traffic control use.
The equipment consists of two units, the transceiver and the control unit. Two alternative control units are available which either provide manual selection only of frequency or manual selection of frequency plus 30 preset channels. Both control units incorporate a built-in test equipment facility to check output power, modulation depth, and receiver sensitivity. A non-volatile store is used to provide the preset channel memory.
The ESD1741 is designed such that it can control two transceivers, one V.H.F. and the other U.H.F.
Power for the transmitter and control unit is taken from the aircraft +28V d .c. supply.
The Brochure D0420 states that the equipment came from GEC-Marconi Radar and Defence Systems at Portsmouth and is dated 1996 suggesting that the equipment is at Rochester either for the Nimrod or Merlin programmes. Another source suggests that the PV1753 number is a Plessey number.

Radio Control unit in general provides VHF and/or UHF frequency selection by means of continuous selection or it may also have preset channels. The frequency and channel will be displayed by a legend through a window on the older units or by an electronic display on later units. There may be a volume control and built-in-test.
