Propagation Summary :: 21.0 - 21.45 MHz (15m)

The 15 meter band has long been considered a prime DX band during solar cycle maxima, but it is sensitive to changing solar activity.
During peak years, 15 meters is reliable for daytime F2 layer DXing and will often stay open well into the night.
During periods of moderate solar activity, 15 meters is basically a daytime-only band, closing shortly after sunset.
During solar minimum periods, 15 meters may not open at all except for infrequent north-south trans-equatorial circuits.
Sporadic E is observed occasionally in early summer and midwinter, although this is not common and the effects are not as pronounced as on the higher frequencies.
