Pirate Radio on 1206kHz?

This morning I came across a strange pattern noise or sound on the MW band.

The radio wave must have been strong as even my YAESU VX-8D amateur radio could be received. Now China and Taiwan broadcast on 1206kHz near my country. In short, I might have received either Radio Taiwan International or Yanbian People's Broadcasting Station.

A legend radio Sony ICF-2010(ICF-2001D) and Sangean ATS-909X can also be received. This is not an internal spurious noise.

I recorded the sound, here.

The strange noise is such as short repeated sound generated by scratches of the CD. This broadcasting station may not manage their owned CDs properly. Intentionally or unintentionally, the scratched CD sound must have been on the air as a result.


The noise or sound has been continued more than 30min. At 5:30 JST(at 20:30 UTC, October 7th) the noise or sound has been faded out then new musics with clear sound has started instead.

Although I doubt the medium wave a Chinese or a North Korean pirate radio for the first time I heard, at last I found the medium wave Yanbian People's Broadcasting Station spoken to Korean language.

That was an interesting broadcasting accident.

Rotten Bar?

I dug my shed and found an unknown bar blown the powders.

Many white powders wrapped around the unknown.

The unknown is composed of a plastic part and blue something. The plastic part is combined with a flat metal part.

And it seems the metal part connects to a black wire.

The opposite side is like this,

There's a rust marked X on the metal.


I compare the unknown object with my AA alkaline battery. The metal part of the unknown is similar to minus poles of AA batteries.

But the hight of the unknown is taller than the AA battery. The white powder and the blue somehing might be alkaline electrolyte, dissolved the surface package and the film. Then, they might have got hard, I imagine.

Long time ago the unknown might be a AA battery "MARK X".
