HF scientific system?

While watching some freqs around 4500.0 kHz, I saw a carrier moving up on frequencies.
I have made some screenshots & I/Q recs, trying to catch burst duration & scanning rate.

The total burst duration was approx. 1.823ms (515ms+ 89ms break + 1219ms)
Scan step was 3kHz
Scan rate was ~65kHz/min
