However, the elipse you refer to can be identified fairly quickly once the operators KNOW that's a transmission they want to located.
Air assets can do the rest. See the previous posts notes on Predator. I have worked with Predator operators.

You keep assuming the 'rabbit' doesn't have eyes, ears, can't listen for/view the opfor which have their own unique RF signatures (radio traffic, telemetry; useful for 'early warning' of opfor in the area) ... I'm getting strong impressions you've done zero field work in the area of HF DF ... filing reports, making sure the gear works (maintenance) is a far cry from actually having iden'td, tracked down and located an HF source, of any kind (carrier, impulse noise, foreign broadcast source, etc).
