This past weekend the HF bands were very busy. It was due to the CQ WW WPX SSB contest. It took me a while to figure out what was the contest and the exchange.
Looking around about this contest information I came across a very useful website I am sure it will be useful for others. It list the ongoing contest and important information about them.
