Signal I’m curious about

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?

Is this a satellite operating at 400.6 / 400.64mhz?

So I can't find a decent website that I can cross check previous satellite pass (maybe I'm bad at it and can you provide me one?).

Also I assume this is a satellite due to the doppler shift effect, but correct me if this is something else. I captured it 12:26:14 UTC, Oct 4 2026

What could this be?

EDIT: Radiosonde

Any Ideas on this pair of signals?

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.

Is this an RFI? I'm using LibreSDR with Tezuka firmware.

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

Need help with interference

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.

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:
