When shooting skip, which is what I used my station for 95% of the time, I can't help but notice all these, what I'm assuming to be club prefixes before stations use their digit call sign..i myself just using my 3 digit call sign. Are these clubs that can be joined in order to get that prefix? I would also like someone to explain to me why or even if this is necessary on 11 meters. I'm assuming it stops any confusion between two or more stations with the same call sign. Are these legitimate...
