Roelof, ah, yes, I had overlooked that Trond had already mentioned Fx = 12.700 kHz. According to your measurement, and in analogy to F8 but with F0 replaced by the alternate 781.25, this one should p
Hello all, This morning the Russian hyperbolic positiion system Alpha is transmitting on three extra frequencies. See attached screenshot. 73, Roelof Bakker, pa0rdt Attachment: Multiple Alpha's.jpg D
Yes the "new" Alpha Fx frequency does fit the supposed pattern; the central peak is exactly at Fx = 12695.3125 Hz. On the F2 frequency, the central line happens to be notched at this location, due to
