Due to logistics, the XF3RR DXpedition is postponed until the first months of 2010.
This operation is organized by the Radio Club Cancun and it will be a low scale operation as the island is a protected area of the government of Mexico so it is subject to many restrictions including not carrying much equipment or more than 4 people at once.
XF3RR will work 15m to 80m preferably SSB and RTTY. QSL via EB7DX.
Update: They have a website online at http://www.xf3rr.net/
