This is such a unique game. It was very intriguing and I tried my best to find the spot but I couldn't. I had the whole island explored. I just couldn't figure out where to go. I was in the top right area of the island.
But that might a skill issue. I think I explored the whole island before I figured out I needed to turn on the radio. I thought I am just not getting any signal.
Great game. I would love some improvements like allowing to move more than one tile because it was annoying to click every tile.
Good luck :)
