3823Kc rushing noise ?

[WA3VJB]

What's the deal on the low-level rushing noise on or about 3823Kc in the evenings?

Sounds like possible DRM from Europe since I don't hear it unless I also am hearing the south American time station on 3810Kc.

Here's Frank, K3SQP last night with an example.

I heard this a few weeks ago.  One of the hams on the Canandian AM group listened to some distorted modulation and figured that it was the 4th harmonic from an AM broadcast station in Buffalo.    I haven't heard it in a while, maybe its the same interference returning.   Last night I could hear what appeared to be the 2nd harmonic of a few of the 160M CW contest stations from 3600 to around 3630.   I thought they could have been receiver images.    Checking on 160, and switching back on forth to 80 on the digital rice box, I could hear the stations on 160, but could not hear harmonics of nearby stronger 160M stations.    From that, I presume I was hearing actual 2nd harmonics.   The 80 meter harmonics peaked up when the antenna tuner was tuned for 80 but did not when tuned for 160.

That was on there last winter too. Definitely coming from the NE direction.

Speaklng of BC station harmonics, I heard one from WPHT, 1210 out of Philly today (used to be WCAU) on 3630 kHz. IIRC, someone much closer reported hearing a harmonic from this station a few month ago on this forum. I'm over 200 miles from Philly. I wouldn't think I should be hear this!
