Propduffer noted:
The radar that tracked MH-370 is at 5°25'28"N 100°15'8"E and is visible with Google Earth. It is a Selex Sistemi Integrati RAT-31.
If there is good radar track available, it is peculiar that it has not been made freely available, especially as the radar is a commercially available item.
Still wonder about the extent of the coverage, 500km range would be for something way higher than MH370 and we do not have a clear flight profile.
