All you need is your original license, your passport, and a copy of each, which they retain for their records. Henry had done this many times before, so it went quickly and smoothly. We arrived at Henry's small hotel in a small village 15 miles from the airport. He lives high on a hillside with 30 mile views to the east, north, and west. From the hamshack room, you have a large panoramic view over 180 degrees way out to the volcanic mountains.
Big picture windows all around, and fantastic views.
However, the place to be when propagation is bad is at a low latitude, and when you have primarily north-south propagation, there is someone to talk to.
