Principally, it simply implies that the ISS is prepared and keen to obtain radio transmissions from you!
In fact, you will have a number of issues so as to contact the astronauts aboard the ISS.
To contact the ISS utilizing ham radio, you may want an antenna, transceiver, and a radio license.

You technically do not want a selected antenna, however you may need with with a large space of protection, like an omni-directional base antenna.
You will additionally want a license permitting you to function a ham radio, which is managed by the Federal Communications Fee in the USA. There are three license courses, however even essentially the most fundamental one will enable you legally talk with the ISS. An examination is required to get a radio operator license.
