Faint "digital" signal next to one of the many China Radio International signals

This caught my eye while scanning the bands, having a coffee this morning.

Couldn't really identify it. Audio attached.

    It looks like a modulation sideband from the Radio China broadcast station, I'd guess it was similar on the others sideband too. The music played on Radio China, tends to include a lot of flute type instruments, which produce extended sidebands with regular harmonic patterns that can resemble data type signals on the waterfall.

    There are also Chinese jamming signals that attempt to make the Voice of Hope unusable, that also sound a bit like data, but I don't think that is what you have received in this instance.

    I don't think this forum allows the attachment of audio recordings, so you maybe better off asking questions like this on the UDXF IO forum.

    OK I think that is broadcast jamming.

    Maybe something like this.
