10-Meter-Band

In the 10 - meter band is a band in the shortwave spectrum. The 10 meter band is the frequency range from 28 MHz to 29.7 MHz. It forms the transition from the short waves to the ultra-short waves. Atmospheric disturbances ( such as thunderstorms ) make rarely noticeable, but probably artificial disturbances, for example spark.

Propagation conditions

Near the bottom of the 10 meter band yet reached stations in 20 to 30 kilometers away. The range can be increased by various influences. Basically you get with a larger radio antenna on higher positions a longer range. In addition to the transmission power and the reflection of the ionosphere is critical for the range.

The transmission path over the space wave must be on the dayside of the Earth. Only in lower latitudes wireless connections are possible via space wave after dusk or at night. About the skywave radio stations are partially accessible at a distance of 2000 km and more.

With a high number of sunspots but also during the day intercontinental connections, even with the smallest transmission power ( less than one watt ) and small antennas are possible.

In sunspot minimum DX connections of up to 2,000 kilometers above the sporadic E layer are only occasionally possible from May to August.

10-meter amateur band

The 10 meter band was founded in 1927 reserved for amateur radio.
