1325 - S5 - weak audio. Band is quiet. Not bad for 1kW station.

This station is usually jammed by China, and they use another broadcast station (CNR1) to do it instead of noise or the music known as the Firedrake. Did you hear positive station ID or anything else to distinguish the broadcast? Without that, you have to assume that it's the jammer.

Check it for yourself. It was music, no jammy sound.
Not besmirching your obvious majestic qualifications, but Occam's Razor applies here. Signal heard. In Cantonese (as far as my white ass can decihper Cantonese). On frequency. How important are you or your precise observations?
Point here is I observe something and maybe you validate it? Am I not able to post unless there is a QSL card return in the box?
Otherwise the forum devolves into some thing where I assert reception and it is non negotiable from there.

No need for snark. Occam's razor says that SOH is a very hard copy and the Chinese are dedicated jammers, and that the fact that they jam with a broadcast station makes it very hard to tell when it's that broadcast station instead of the low power clandestine. ESPECIALLy when you hear music.
Your posts need no validation. This isn't about feeling good about ourselves, it's about knowing what we're hearing. Your answer is defensive and in no way exhibits Mandarin fluency, so I will go with Occams Razor and conclude that you heard CNR1.

Thanks for the pointer. I listened again this morning, found the same station on 10820kHz much stronger, and at the same time pulled that frequency up on the Hong Kong Kiwi SDR, and listened to both Kiwi and my radio. Sure enough strong station there, but at TOH it signed off and then there was a much weaker signal still there, while I could hear nothing on my radio. Checked back to 6870 and same weaker station there.
The weaker station, though, seemed awfully weak for being only 500 miles away at 1kw at night.
Need to brush up on Chinese...

I thought SOH ran 100 watts not 1000. I tried for years to log them but was not able to.
It is possible to tentatively ID SOH tx's by checking RFA tx's which many SOH's relay for up to 20 hours a day. Of the audio matches.....
Conversely one can ID the jammer by comparing it to a known CNR 1 tx. If you can match the audio to a known CNR 1 then what you are hearing is the jammer and not the wily, elusive SOH.
