The QSL fees may be reasonable considering the demand.  I'm surprised it is so rare as the Chilian Navy is there and can land a 737.  San Felix should be as easy as Easter Island to work. It will be an ATNO for many but Honor Roll for N5QS!  I may try to pick up band counters which weren't considered forty years ago.

This is not a DXP, but a DX Activity as only one operator on the island.  The plan is to be active 24/7 with two stations on the island.
    One station focused on SSB/FT8
    A remote station focused on CW/FT8

Looks like he's prioritizing his responses for QSL Cards and LoTW by "donations".  ADXD #14.  The question becomes send $10 after a contact (or two) or send $30 BEFORE they leave and hope for a contact.
