Course-discovering, or fox looking, is a well-known action in ham radio circles the place a team of people today armed with radios attempt to track down a broadcasting supply. Apart from becoming a hobby for amateurs, it’s also a important instrument in the belt of regulators who are trying to keep track of down violators of the air place. There are a large amount of means to determine out the specific location of a radio transmission, but this a single manages to pull it off making use of both of those a boat and a Steam Deck, each individual armed with a application-described radio.
This challenge arrives to us from [Aaron] who is perfectly known in the novice radio circles for his SDR-focused Linux distribution termed DragonOS which has all the applications needed for a high quality SDR working experience, in this scenario KrakenSDR and DF Aggregator. He’s loaded almost everything up on a Steam Deck and remaining that in a protected spot on the shore of a lake, whilst he carries second unit with the very same software with him on a boat. With the two units listening for a certain signal, he’s equipped to immediately zero in on his buddy on the shore who is broadcasting on the 70 cm band thanks to the enable of all of these software program offers.
Although ham radio isn’t generally acknowledged for getting a youthful and fascinating exercise, the introduction of program-defined radio and other digital modes seem to be to be shaking matters up in that environment. Unquestionably speeding all-around a lake on a boat is exciting on its personal as very well, and a fox hunt like this can be carried out with one thing as tiny and basic as a Raspberry Pi as well.
