Nothing on 6889 at home (not a proof)

Something on Chichester 5to8, and more of that on Weston 8074,
sounds like a British broadcast with sports report?
listening well, there's music below that

So I think this is overloading of the Kiwi SDRs with big antennas. I often heard that on lower SW frequencies.

edit : yes, that's // with 693 and 909 (very strong signals)

I'm going to rename that topic as  Overloading of British KiwiSDRs

hello ray, im listening on one of the weston sdr's (http://80m.loginto.me:8075/)

so this is probably an image? is it common for kiwi sdr's as well to produce them? maybe someone can clarify if that would happen at this frequency

Finding the formula for the overloading product will be difficult without knowing what is the other signal in the mixing product. And 6889 is not even a multiple of 9.

So remind the clues :
- not a mutiple of 5 kHz
- at night
- some second audio in the background

and go listening through other KiwiSDRs in Europe to check if there is really something on the same frequency.
