Still receiving same high RF - as I constantly monitor ch.25 from 1418 to 1500 (tc=1132). Sea state is picking up. John noted lanyard(sp.) to hydrophone was out on #12 buoy. I continue to review tapes from buoy #11 while return to DEW site. Weather conditions have worsened by dinner with clouds over the ocean which creep in to shore with a snow flurry. Temperatures in 20's with a slight improvement in visibility. Water noise is higher but not as poor as earlier buoys #11 and #12." Ampex Videocassette T120 box notes: "13-1. 9/27/86.
