For the last weekend of May, a big event: the CW portion of the CQ WW WPX contest!
The rules are similar to the SSB WPX Contest, which took place last March.
Again we stress that the focus is on working as many prefixes as possible.
On CQ magazine web site, you can find the exact definition of ‘prefix’ and its exceptions. Complete rules can be found here: http://www.cqwpx.com/rules.htm.
The contest will be taking place over the full 48 hour period of Saturday and Sunday (UTC time). A list of stations that have announced their participation can be found at www.ng3k.com/Misc/wpxc2017.html. Good hunting!
