Here is a detailed breakdown of the jamming types, purposes, and frequencies shown in your files.
1. Fast Sweep / Stepper Jamming
File: 1140.jpg
Frequency: ~11.500 MHz (25-meter Broadcast Band)

2. "Wobble" or Oscillatory Jamming
Files: 1137.jpg (~13.044 MHz) and 1134.jpg (~12.715 MHz)
Frequency: 13 MHz and 12 MHz (Maritime/Aeronautical Bands)
████████████████████████ [REDACTED / 1 SOURCE PARAGRAPH / PUBLIC EDITION]
* How it works: The jamming carrier frequency is slowly modulated (wobbled) up and down. Unlike the fast sweep above, this sweep is slower, creating a "swirling" or "herringbone" pattern on the waterfall.

3. Noise / "Bubble" Jamming
File: 1146.jpg
Frequency: ~6.400 MHz (49-meter Broadcast Band)

4. Wideband Barrage / Noise
File: 1143.jpg
Frequency: ~8.151 MHz (Maritime Band)
████████████████████████ [REDACTED / 2 SOURCE PARAGRAPHS / PUBLIC EDITION]
* Purpose: Disruption of tactical datalinks or voice comms. 8 MHz is a common band for maritime operations; jamming here is often used to deny coordination between vessels or ground stations.

These waterfalls indicate a sophisticated RF environment where different techniques are being applied depending on the nature of the target (broadcast voice vs. utility data).
