Notes:

This Radio Control Unit is similar to C0184 and interestingly has a legend that suggests it was made by Gables Engineering in the USA. The National Archives hold a record of this equipment being used in acceptance trials of Elliott 21 VHF and Marconi AD 260 VOR installed in a Beverley C Mk 1 transport aircraft in 1966.

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.
