Once the Office of Management and Budget (OMB) approves the FCC's Report & Order for the 630 meter band, radio amateurs in the United States will be able to use frequencies between 472 kHz and 479 kHz, subject to various restrictions on antennas and power. The FCC Report & Order also covers operations in the 2200 meter band (137 kHz).
If you're curious about what the new band means for radio amateurs and the type of equipment needed to get on 630 meters, then this simple tutorial from Dr. George Smart (M1GEO) will help you get started.
The report is divided into four separate pages, each with supporting photos, graphs, reception reports, and other operating data:
472 kHz antennas
472 kHz receive preamp
472 kHz transverter
472 kHz transmitter
Dr. Smart also provides a helpful youtube video discussing individual pieces of hardware needed to get on 630 meters.
I found the tutorial easy to read and fully illustrated with diagrams, schematics, photos, and performance data.
