F6BEE Jacques told me before leaving Tahiti (TX4T) : "If you can, try to go to Marquesas".
I have made a lot of professional trips to Nuku Hiva but only during 1 day. 1 month ago, I found a good place for ham radio in the north of the island. A good place to work JA EU and USA.
Amateur radio is really not popular here. It is mainly done by expatriates in Mali as most nationals can't afford it. The required equipment is very expensive and license fees are too high (wages are very low).
