A guy on the Subsim.com website is trying to model more realistic SJ radar sets for the Silent Hunter IV game. He read some material that stated that contacts looked like 5 degree arcs on the scope (due to its accuracy), as opposed to a dot. Is this true? Also, he wanted t know if SJ radar had a sweep line or did the operator have to pay attention to the radar bearing indicator? Finally, did any of the SJ radar sets have a range and/or bearing "odometer"? I know that the SS radar on the Batfish does.
A follow-up question is how far out do contacts show up on the PPI scope? I thin the max. range is something like 80,000 yards/46 miles, but do contacts really show up that far out?
Thanks.
