• Annotazioni

• Mimco all-wave marine broadcast receiver.

  A receiver designed especially for use in all classes of sea-going vessels, from passenger liners to trawlers, so that broadcast programs may be received and relayed to different parts of the ship, has been introduced by The Marconi International Marine Communication Company, Marconi House, Chelmsford, Essex.

  The receiver, which is known as the Mimco, consists of a Dynatron manufactured sensitive 9-valve superheterodyne receiver and an audio power amplifier. The receiver unit is common to all installations, but the power amplifier is chosen according to the number of loudspeakers employed. A 10-watt unit suffices for small installations with up to 10 extension speakers and these and the receiver can be housed in a single cabinet measuring 251 x 19 x 131 in and weighing 90 lb.

  Short, medium, and long waves are covered in four bands, their respective tuning ranges being 10 to 32 metres, 30 to 85 metres, 180 to 570 metres and 800 to 2,000 metres.

  A tuned RF stage is employed, also variable bandwidth in the IF amplifier, the five switch positions corresponding to 5-, 10-, 15- and 20-kc/s bandwidth. There is a tone control.

  The receiver takes 95 watts from AC mains of either 115 V or 230 V of 40 to 80 c/s.
  If required, a converter can be supplied for operation on 110 or 220 V DC.
