this morning I tuned across a broadcast with a British accented speaker gving a sort of comedy speech or routine. The broadcast cut out at 7am PST and I searched onlne and here but did not have any immediate hits.
-
So far the only hits I get for 5812 are related to spy number stations. Maybe somebody selected the wrong audio path and sent out normal audio programming instead of a spy numbers broadcast.
-
that almost sounds like a spurious harmonic maybe generated from another station ? (didnt actually hear it)
-
Was super strong and listened to it for 10 or 15 minutes and right at the top of the hour it cut out. At first I thought I was listening to a regular SW broadcast and wanted to switch to the station's other frequency. Then I was unable to get a match anywhere

hmmm, maybe it was a user error on a numbers station.
was it in AM or SSB ?
-
was in AM and good audio quality
Forgot to say that I thought through your suggestions of harmonics (good idea!) and looked at these
2406 KHz second harmonic
11,624 KHz sub harmonic
17436 Khz sub harmonic
I could not readily match those up with a legit broadcaster but 17436 shows up with hits for a numbers station
-
ahh, wish you recorded the I/Q baseband.
its hard to say what it was that you may have heard.
i have heard some "interesting" harmonics in the past from legit stations and amateur radio ops.

Was thinking some more about this and it may be my error. Right now I can hear a Spanish Language broadcast in AM Wide while tuned at 5812 KHz but the station is actually at 5810 KHz and is EWTN/WEWN. Based on schedules it was not EWTN that I heard (in first post) but maybe it was the Beeb's World Service? They do broadcast on 5810
