“CQ contest ” in the ear just reverberation has just dispersed, cq ww SSB contest is about to kick off. To participate in the DX competition, BY3MM is a new radio station, which is located in the urban environment and the venue of the limited antenna under conditions such as will certainly affect the DX race to obtain good grades, but in order to enhance technical operation and training team, the atmosphere of active competition, BY3MM decided to MS group to participate in this competition.
