Morse code circuit. ( This unit produces a morse code type sound in a built in speaker in the Radio, when the corresponding morse key is plugged in and operated, the Morse key plug in port is on the  lower right hand front side of the " Radio " )

printed circuit of morse code oscillator, ( trying out        printed circuit in final place, with extra metal 
different fitting options here.)                                              work for supporting wiring.

printed circuit of the morse oscillator and variable pitch control ( Potentiometer ) in place, this is the circuit which produces the variable  pitch morse code sound, they are connected together with the Red, Brown, & Blue, wires.

here we have a genuine morse key plugged in to the Morse code circuit plug on  the front of the panel.

rear view of "Radio" faceplate showing connections at the back of the connector strip, the mores key plug in point is the one on the left,  ( white square)

the next group of connectors  ( group of three ) to the right of white square is for the Microphone it will plug in but  is non working,
the next two pairs of connectors two are for earphones these can be connected to the morse key circuit
so you can hear the out put tone from the morse circuit  in the earphone's when you operate the morse key. 

Below rear view of radio face plate,  Two individual connectors make up one individual connection point at rear of  radio faceplate,   this particular one is the plug in point for the morse key .
