I think this is the right place... Found this signal which appears to be morse code to my very untrained ear, a pattern that seems to be the letters U L O (dot dot dash dot dash dot dot dash dash dash) [
EDIT: first letter is W, dot
dash dash] followed by four long shrill pulses, in a pattern that takes about 15 seconds. I apologize that the audio wasn't great on my video. I searched a bit online and here but couldn't come up with anything describing this transmission at this frequency.
