Amateur Radio 40 m Band
|
According to the ITU, "the 7 MHz band is heavily used 24 hours each day. During daylight hours, the band carries the bulk of amateur sky wave communication over distances of less than 1 300 km."
The band is commonly referred to as the 40 m band, because of its approximate wavelength.
In ITU Regions 1 & 3, the band 7200 - 7300 kHz is allocated to broadcasting instead of amateur radio. The high power, long distance broadcast signals often interfere with Region 2 amateur radio operations in this band segment, especially at night.
In the U.S., the ARRL has adopted the following band plan. The plan may apply in other countries as well. Following the band plan are the band segments that are authorized for the specified U.S. licensee classes.
