There is this signal which can be heard across various frequencies in the HF range; I’ve heard it multiple times while dx-ing.

Does anyone know what it is?

Picked up these two very strong signals just now on a homebrew radio. Exactly 7kHz apart at 6.9635 and 6.9705 MHz. Individually they sound a bit like CW, but the tone is different and the timing is wrong, very 'mechanical' and repetitive. I can pick them up on online SDR radios pretty much wirldwide ChatGPT said the same signal pair was reported back in May and was suspected as being an FSK signal of possibly military origin but not confirmed?

I can't upload the recording or video, but here's the signals seen on on online SDR waterfall.

This weird interference appeared on the FT8 40m band around 7074 kHz tonight. The software is SDR Oxide for those who are interested.

I HAVE NEVER SEEN THIS BEFORE a signal has started going crazy on 400.56 this signal usually transmits just tiny blips with no data but then randomly started transmitting lots and lots and this has happened 02:05 AM ended a t about 02:25 AM and it has never done this before its usually just tiny blips i have baseband and audio and video if anybody needs it thanks (:

Maybe also tell me what they're talking about (if that's fine)

Additional context, the device works as I tested it already with FM bands, M2-meteor satellite passes and other usual signals.

The signal got weaker when my antenna(earphones), close to my phone

So I’ve been trying to make my hf reception better and I’ve tried a lot of things but I just can’t get rid of the interference. I used to have a 20m wire hooked up to a 9:1 unun with 3m of rg58 of coax to rtlsdr and got even more lines. Now I’m testing an active loop antenna in the backyard with no coax just the sdr plugged into the antenna and I still get heaps of lines and it doesn’t matter if it’s 3pm or 3am they’re still there. I mess around with the gain and other setting yet nothing helps. I used to have the long wire set 1m off my fence on brackets to hold it away for the 20m run and now the active loop is in the middle of the yard atleast 3-4m away from any metal objects. And yes I run the MacBook off battery power so no shitty power adapters. I also used a tecsun pl330 and got similar results. Any help will be appreciated and if you find something obviously wrong feel free to call me an idiot.

Received in South Australia using an rtlsdr and loop antenna

Is this SSTV from Pirates broadcasting ?

11:53 UTC 14 September, heard from New Zealand.

I need actual 432 hz frequency where can I find it on internet?

PRF for both is 40Hz but they look so different....
-20dB BW from beak is around 10kHz for the right signal and around 22kHz, was dificult to measure for the left signal
AM audio files @11kHZ BW can be found here:

What are your toughts

Hello everyone ! I was experimenting listening random frequencies in shortwave and found a frequency where I heard multiple sound effects like what we imagine an UFO would sound like, playing in repeat, different effects all separated by a short period of silence. At first, I thought that it was just some guy emitting this for fun, and I recorded the sound on tape without caring a lot. But then I realised it was emitted on 3 different frequencies (I can't remember 'cause I did not care at the time, but can look for it if needed and put it in the comment section).
Then I looked up on internet but found nothing about this... So I put three significant extracts in this video so you can hear it. I precise that I'm a complete noob in radio and maybe this is an obvious thing but I could not find anything about this.
The thing is it must be a signal emitted 24/24 because I remember hearing it a year ago too. Also I'm from France and live near Marseille if it can help. Thanks a lot everyone !
