The 15-meter band is an amateur radio frequency band from 21 to 21.45 MHz, suitable for long-distance communications via ionospheric reflection. Learn about its history, frequency allocation, and band plans for different countries and regions.
Learn about the characteristics and conditions of each amateur radio band, from 160 meters to 10 meters. Find out how 15 meters is similar to 20 meters but more influenced by the sunspot cycle.
The basics on starting on the 21 MHz or 15 metre HF band. A must watch as propagation on this band will get better and better as solar activity increases.
4 sty 2018 · Here is video #3 in the mini series, learning about 15 meters, one band at a time.
15 Metres, 21.0 – 21.45MHz. The 15 metre band is a wide allocation with plenty of space for all. It is an excellent DX band and is open for much longer and through more of the sunspot cycle than 10 metres.
25 wrz 2024 · The 15-meter band (also called the 21-MHz band or 15 meters) is an amateur radio frequency band spanning the shortwave spectrum from 21 to 21.45 MHz. The band is suitable for amateur long-distance communications , and such use is permitted in nearly all countries.
4 mar 2024 · 15 meters (21.000 – 21.450 MHz) The 15 meters band is most useful during solar maximum and generally a daytime band. Daytime sporadic E propagation occasionally occurs on this band, allowing for communication over distances of up to 1,500 km (1,000 miles).
