Propagation Summary :: 10.1 - 10.15 MHz (30m)

The 30 meter band is unique because it shares characteristics of both daytime and nighttime bands.
D layer absorption is not a significant factor. Communication up to 3000 km (1900 mi) is typical during the daytime, and this extends halfway around the world via all-darkness paths.
The band is generally open via F2 on a 24-hour basis, but during a solar minimum, the MUF on some DX paths may drop below 10 MHz at night.
Under these conditions, 30 meters adopts the characteristics of the daytime bands at 14 MHz and higher.
The 30 meter band shows the least variation in conditions over the 11-year solar cycle, thus making it generally useful for long-distance communication anytime.
