Context

Country: Unknown
State/Province: Unknown
Period: Unknown
Canada: Equipment developed under contract, to specifications of Defence Research Board, radio physics laboratory, Ottawa. Wanted to place it in orbit with a satellite.
Function: Access panel used to cover electrical connections for the recorder that can be removed for service.
Technical: The transmitter sweeps all or part of the HF frequency range, transmitting short pulses. These pulses are reflected at various layers of the ionosphere, at heights of 100-400 km, and their echoes are received by the receiver and analyzed by the control system. The result is displayed in the form of an ionogram, a graph of reflection height (actually time between transmission and reception of pulse) versus carrier frequency. An ionosonde is used for finding the optimum operation frequencies for broadcasts or two-way communications in the high frequency range.
Area Notes: Unknown
