Considering drones contain no real pilot (player), I don't believe the radar detects them. Otherwise each dot for a bomber formation would be three dots. So the height at which drones fly is irrelevant.
Base flash has nothing to do with radar. Its purpose is to represent the local population calling in to the base and saying "I see bad guy planes," hence the lack of directionality or dots. However, it seems to me a base ought to flash long before radar contacts are made in that case (as is generally the case in scenarios).

Sure, if you have greater than/less than keys...except the AHBBS rejects HTML. My old phone (before I got a smartphone) had brackets on the pound key, though.
