If all yopu want is DX then forgot all about 2m or 6m and go get your general ticket as you have been told before. 2m SSB is very sparse and is not really DX. Sure a few hundred miles and rarely somewhat further but you need a fairly large yagi at a decent height and it MUST me horizontal. For 6m a small three element yagi is half decent but larger is markedly better but openings are unpredictable and often last about 10 minutes. Sometimes in the summer openings may last hours however. Again, unpredictable. Get your general at least.
