Solid Core Connection and Coil Wire



Solid core wire is used as it plugs into the breadboard more easily than stranded wire.  Enameled copper wire is more normally used for winding the coils, but the insulated copper wire is easier to handle if there is room in the design, and the electrical results are equally good.  The colour of the insulation may differ.  About three metres is used to wind the two radio coils and 1 metre for the other interconnections to the speaker, variable capacitor, and to make the wire jumpers used on the breadboard.
