INDICATOR ID-60/APA-10
 year 1944 USA

Panoramic Adapter is an equipment which is used with certain receivers to picture on the screen of a chatode tube aportion of the radio spectrum. The panoramic input of the adapter is taken from the i-f section of the associated receiver.An oscillator within the adapter beats against this input frequency and another intermediate frequency is produced: this is the i-f frequency of the adapter and is 3.9 megacycles for A,B and C channels.The oscillator within the adapter is modulated.
