  • Anotaciones
  • The heterodyne type 357 has been specially designed for use with the receiver Type 352. It covers a wave range from 200 to 22,000 meters in 5 wavebands and is for use on CW signals only.

    The heterodyne uses a simple oscillator circuit which is coupled to the receiver by means of a coupling capacity, contained within the device. A large HT choke and a decoupling condenser prevent feedback to the receiver via the battery or battery leads.

    The heterodyne comes with a calibration chart that gives instructions about wave range switch and tuning condenser position for each desired wave length.
