What are the basics of AM radio receivers?

In the early days of what is now known as early radio transmissions, say about 100 years ago, signals were generated by various means but only up to the L.F. region.

Communication was by way of mores code much in the form that a short transmission denoted a dot (dit) and a longer transmission was a dash (dah). This was the only form of radio transmission until the 1920’s and only of use to the military, commercial telegraphs companies and amateur experimenters.
