Unidentified Radar (or QRM) on 20840
From Signal Identification Wiki
This weak pulsed signal may be an OTHOver The Horizon (very long range) radar, or it could be QRM. Pulse repetition rate is about 80 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz).. There doesn't seem to be any modulation on pulse which indicates that this may not be a military radar after all. Research radar is also a possibility.
