Next Global HF Weekend: 

March 30-April 2, 2017
It's still a couple weeks away, so be sure to mark the next Global HF Pirate Weekend on your calendar. 

The idea behind the Global HF Weekends are to promote friendship through radio around the world. The hope is that listeners will be able to hear different stations and for broadcasters to reach distant locations. Anyone may participate. I've already heard from a few stations who plan to broadcast and I've been in contact with a number of listeners.

The last one, which occurred during the first weekend in November was a sort of trial run. Cupid Radio and Mike Radio were both widely reported in North America, and the former even made it to Japan. Sluwe Vos Radio wasn't reported as much in North America, but it was reported in Brazil during the last GHF weekend.

March 30-April 2, 2017
General frequency ranges:
15010-15100 kHz
21455-21550 kHz

Basic schedule:
European morning, 0800-1200 UTC from Europe to Asia/Japan/Oceania.
European afternoon, 1200-1600 UTC from Europe to North America and vice versa.
European night, 2200-2400 UTC from North America to Asia/Oceania.

Of course, these were general frequency ranges used by pirates during prior Global HF Pirate weekends. Some stations will surely operate on frequencies and times outside of these ranges. In fact, the way conditions have been lately, frequencies at or below 15 MHz seem like they will be more effective for intercontinental broadcasting. 

These will be updated on HF Underground (https://www.hfunderground.com/) and on the Hobby Broadcasting (http://hobbybroadcasting.blogspot.com/) blog as it happens.
