When the band is open, 10 meters is the band for QRP DXing–great DX can be worked with very low power and very modest antennas.
The entire world congregates on 10 meters on the second full weekend of December for the ARRL 10 Meter Contest. This year this contest falls on the weekend of December 8-9, 2012. Complete rules can be found here: www.arrl.org/10-meter. It is worthwhile to note that this contest allows participation by both CW and phone operators.
We are approaching the peak of sunspot cycle 24 and conditions on 10 meters should be excellent for working DX. Even those not interested in the contest per se should take advantage of the propagation and the sheer numbers of DX stations on the band to work some “new ones”.
