Any ideas as to what I might be picking up on SDR? They make for some strange patterns. Picked them up at the following coordinates: (31.514596, 74.345092) using GQRX, tuned to 217.25 MHz. As for the second snapshot, I'm not sure what the exact frequency was but it was close to 217.25 MHz.
According to https://fccid.io/frequency-explorer.php?lower=217.2&upper= it might be European television broadcasting. What is your location?
