Frontal view.

Orthogonal view. The instrument controls stick out from the window on the main chassis.

Back view. The back panel flap down to access the innner area.

The back panel was removed to show the innner area as well.

Electronics and air antenna coils are mounted on a single panel. The panel can be suitably extracted from the main chassis.

The electronics are held inside a internal metal enclosure. Antenna coils are hand wound with #32 AVG enameled copper wire.

The instruments controls are mounted on the frontal panel of the internal enclosure. Note the prototype circuit built on a perforated board.

On the back panel of the internal enclosure are located the trimming screws of the oscillators frequency.

Hi,

I would be interested to have a copy of the circuit diagram (and coil specs) that you used. Any chance you could add them to the story?
