Signal been captured around 2 years ago. And all time it has static frequency, power and data. I think, it maybe a radar, but not found any similar records there. If i go near to S.Petersburg, power of signal increases. Also, it maybe a beacon. If i try to decode it by PSKPhase-Shift Keying or FSKFrequency-Shift Keying, i has non repetitive data, separated by some of 0 or F's.
