via HACKADAY: An Autonomous Drone For Working Rare Squares

Amateur radio is an extremely broad church when it comes to the numerous different activities that it covers. Most of the stories featuring radio amateurs that we cover here have involved home-made radios, but that represents a surprisingly small subset of licence holders.

One activity that captivates many operators is grid square collecting. The map is divided into grid squares, can you make contact with all of them? Land-based squares in Europe and North America are easy, those in some more sparsely populated regions a little less so, and some squares out in the ocean are nigh-on impossible. As an attempt to solve this problem, the Jupiter Research Foundation Amateur Radio Club have put an HF transceiver and associated electronics in a WaveGlider autonomous seagoing vehicle. The idea is that it will traverse the ocean, and you can work it, thus getting the contact you require to add those rarest of grid squares to your list.

The transceiver in question is a commercial portable one, an Elecraft KX3, and the brain of the payload is a Raspberry PI. It’s operating the FT8 mode, and will respond to a call on 14074 kHz in an automated fashion (Or it would, were its status page not telling us that it is offline due to power issues). It’s currently somewhere in the Pacific ocean, having been at sea now for a couple of months.
