Around my location, there is an odd signal near 50.145MHz (at this moment it seems centered around 50.14735MHz but that changes as the day progresses). Other amateur radio operators in this city also hear it; apparently it started about a year ago.
I am curious where it is coming from but do not have equipment for 6m fox-hunting. There was something written once about using existing web-SDR stations to triangulate signals. Is such a thing really practical? If so, how would one go about doing that?
