Has anybody got an idea where the interference in the center of that video snapshot might originate from?
I'm amazed by the almost digital look of the bright/dim changes and the very sharp vertical boundary of the interference.
At app. 120 black/white changes per line, the frequency would be: 625 (PAL) x 25 fps x 120 = 1.875 MHz
given the vertical span of 1/10 of 576 visible lines the duration is 625/(576/10) x 1/25 = 3,5ms interference duration.
1.875MHz for 3.5ms, does that ring any bells?
The setup: test inside residential building,
distance 8 yards, one wall in between, sign
