Meghan and Nels got back from Hooper early so we went down Cathedral and installed the rest of the DTS cable in Cathedral. 4 V-threads used in the tube. Tried to reconfigure using channel 1 and 4 for the Cathedral part (Cathedral far ends are two males, plugged together with F-F adapter), but no signal from channel 1, and trying channel 4 made the red "fault" light come on. Back at the surface, v windy and low viz. I called LEH on iridium with frozen gloves to push back callout.
