342345, The ground acts as the second wire?
qdJzXuisAndVQb2, What do you mean?
342345, (edited ) The spool seems to contain cable with just one wire. To form a circuit two wires are needed.
I assumed that maybe the ground is the second wire.
Edit: exactly what setsneedtofeed said. I just read it afterwards.
jaybone, Can you hear me now?
setsneedtofeed, (edited ) An electrical circuit must be completed to function. Some telegraph designs used only one wire, and used the earth as the return to complete the signal.

The comment was asking if that’s what is happening, since there appears to only be a single wire. I am not an expert on WW1 field telephones, but I do believe a phone can work on the same wire setup as the telegraph. It is a plausible question.
qdJzXuisAndVQb2, Thanks, I had no idea that was how that worked, that’s fascinating.
