If you'd like to see the type information the RadarBox and SBS-1 Mode-S receivers can provide, check out the Sticky Thread for Milair IV in the Maryland forum. Several people on that thread have these Mode-S receivers. While you won't see graphic displays from the systems there, you will see the type information that can be reported by using one. I've been following military air for many years and feel the Mode-S receiver is, by far, the best tool ever made for that part of the hobby. Combine it with the information from your scanner and you've got a remarkable combination helping to visualize what you're hearing. And to confirm what was posted above, the Mode-S receivers provide information in real time - including for military aircraft. With just a radio/scanner, it isn't possible to monitor all frequencies all the time. Very often, Mode-S will provide the first tip that a military aircraft is in the area simply because it is looking at all aircraft, all the time - up to the range of your antenna system.
