280 (ish) khz, beep?

right guys, you adjust the radio, at about 280 kHz, (long wave people:)), I get a strange sound, 8 repeatign tones again and again, the radar has always been there,? do not think his Morse interperetign iv tried using a morse sound application on my pc and returns only trash in English and Russian, if ur near London, I'm just west of it, tune in and see what u think:)

Radiolocation some kind, possibly. (Or you've discovered the foreign spy transmitter on the left before returning to their star system.
