Simply Connect the Included Earphone and attach an Antenna and Ground and it is ready to use.
A minimum of a 30-50ft long outdoor Antenna Wire is recommended.
The best configuration for a crystal radio antenna is to run the wire horizontally between two electrically insulated supports as high off the ground as possible . Search eBay or the net to purchase a "Crystal Radio Antenna" Kit or to make your own..
The reason you need a good length antenna is because the more antenna you have, the more power your set will receive, and the louder it will be.

When Looking thru the various Models of Crystal Radio in my eBay store, you
will see a number of Radio coil Design Variations such as Litz, Enamel, and Center Tap Coils.
I offer these Variations because many Crystal Radio Enthusiasts often prefer one type of coil design over another.
While all of the Coil Designs Perform well in the AM Medium Wave Frequencies, my cost to manufacture these coils
vary and you will see some slight Cost Differences in the selling price depending on the Model.
