Allocator, many thanks for the D008.dat file. Don't worry about the outlines, I'll sort out something myself using my existing Planeplotter outlines.
So far, I'm very pleased with my RB. It's interesting to run both RB and SBS-1 side-by-side, and see aircraft appear in RB about 30 seconds before they appear in Basestation. The SBS-1 goes soon though!
I'll gather a polar diagram over the next few days and then compare coverage. It takes a few days before I've had aircraft in every part of the sky up in the remote north!
