10 Meter Ham Radio Band

The 10-meter radio band consists of frequencies from 28.000 to 29.700 MHz. These frequencies are contained in the Amateur Radio 10 meter frequency band and the FCC requires that the radio operator obtain a license. The FCC considers the 10 meter band acceptable for long range communication.

Communication distance on 10-meter is highly impacted by the 11-year solar cycle. When the cycle is at it's peak, worldwide propagation allows for distant communication with minimum power levels. At times with only 4-12 watts side band communication between the United States and Europe, or Australia is regularly done. Other atmospheric conditions also have an impact on this phenomena known as "skip."

• During the height of a sun spot cycle radio waves reflect off the ionosphere allowing for "skip" or long distance communication.
• During random periods of atmospheric anomalies skip propagation may also occur independent of the solar cycle.
• Direct communication (without skip) can occur from 30 to 50 miles depending on terrain and transmit power.

Skip Phenomena

The "solar wind", generated by the sun's explosions, impacts the earth's upper atmosphere, called the ionosphere. When it does, ionized layers (called "F2" and "F1") form in the ionosphere between about 100 and 300+ miles above the earth's surface. The "F2" layer acts like a mirror to a 10 meter radio signal. The "F2" reflects the signal back to earth, thousands of miles beyond your antenna.
