Dear Andy, LF Group,Well, this is what 137.5k +/- 100Hz has looked like for the past 22 hours or so - quite a bit of impulsive and other noise here! I am seeing quite a lot of the peculiar "double false decodes", i.e. the same ficticious callsign decoded twice during a single transmission period, at different frequencies and with different delta-T. This has happened about 50 times during the period shown on the screen shot, and makes up a large majority of the total number of false decodes. I imagine the probability of this happening actually as a result of random coincidence must be fabulously tiny - so perhaps some artefact of the decoding algorithm, or a software bug?
