Log Notes: "Cruise #65 Puerto Rico Feb. 6 1969. One individual making noises. Then a humpback come in _ not picking him up continuously for awhile at least. Then we pick him up better. Lot of noise at times. Lost bearing then moved ship: Then picked him up good again. Then lost him again _ Now back again. Good sequence. Prob. complete except low freq. missing. BQR got weak for awhile. About 4/5's way thru tape. Then comes back in. About 3 complete calls with some parts missing. Some voice but not all the way thru. To next tape 2 to 8 minutes missed. Movement of BQR head a problem, perhaps."
