ARRL DX Contest — CW

Contest Objective: To encourage W/VE stations to expand knowledge of DX propagation on the HF and MF bands, improve operating skills, and improve station capability by creating a competition in which DX stations may only contact W/VE stations. One contest period is CW-only and one is Phone-only.  Use only the 160, 80, 40, 20, 15, and 10 meter bands.   Begins 0000 UTC Saturday and runs through 2359 UTC Sunday.
