S79GM in the Seychelles will be operated by Gavin, GM0GAV and Rob, GM3YTS (FOC 1430) from March 21st to April 1st. The station will be QRV on all bands with a focus on LF, mostly CW, and some RTTY. http://s79gm.blogspot.com/. Gav and Rob can only transmit above 7050kHz or so on 40M, so look for them on around 7050kHz, listening on 7025kHz or thereabouts.
They will upload some detailed frequency info on their blog. All the QSOs will be uploaded to Logbook of the World when they get home, and they also hope to upload logs during the expedition - keep an eye on http://www.clublog.org/charts/?c=S79GM.
