How do you start on 472 kHz (630m)?

This is a question I am often asked. Many people are under the illusion that huge antennas and extensive grounds are needed. This is definitely not true!! I am sure that if you want to work vast distances then these would help, but I have had great success on WSPR around Europe with just my simple QRP transverter and my earth-electrode "antenna" in the ground. I have also had some international QSOs with these around Europe.
