Thanks. That seems to have helped.
Just had another great patrol (4 Marus sunk off Japan) ruined by a random CTD.
Also, can anyone tell me how to make sense of the radar in TMO/RSRDC? I knew how to get rough ranges with the PPI in stock 1.5, but in TMO, there are the number dials on the left that I'm assuming are supposed to read out the range to the target. However, the only way I can get them to move is by dragging across the monitor with my mouse. They don't correspond to actual range as verified with optics. I'd love to be able to get some solid range/bearings with this new radar, but I can't figure out the number dial. It didn't seem to be covered in the TMO manual (nor the RSRDC readmes).
One more thing, is the Japanese coast in 1942 supposed to be a total turkey shoot? I've yet to encounter much else other than lone Marus (easy pickings).
