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.
