Weak OM talking, lots of fading down into the noise, but heard "blast wave" and "the Japanese cruiser"

2119 UTC - "YO-160" "Pensacola" "LST-52" "ARDC" "only slightly damaged"
2120 UTC - "Wilson" "Stack" "Huge" "LCT-874" "these were the first pictures taken by surface craft"
2121 UTC - "about 1800 yards from the epicenter of the bomb blast"
2122 UTC - switched to Mass. based remote SDR, OM talking about damage to ships, music in background
2123 UTC - big signal increase, now up to S8, "this troop transport received extensive damage" "radio and radar antenna"
2123 UTC - music continues "this ship, the USS Nevada"
2128 UTC - "as a result of the bomb burst" - then more music "damage to the starboard side was less severe"
2129 UTC - dramatic music "Joint Task Force 1"
2130 UTC - "the primary purpose of Test Baker" "resulting from an atomic bomb explosion"
