Thanks for the identification. I'm in Charlottesville, so it is plausible. The receiver is an SDR, the
ADALM-PLUTO followed by the SDR++ software. The difference between 323.127 MHz and 323.125 MHz is 6 ppm, with is within spec for the clock, I'm guessing. Could you provide the url for that milAir list, please? I'm analyzing data from the Green Bank Radio telescope, in the band 300-400 MHz. The data was taken during the Orionid meteor shower, and I'm speculating that a lot of the interference in the data was meteor trail scattering of milAir traffic control UHF over the horizon. I'm looking at the band from here in Charlottesville to compare to the recorded data from Green Bank.
