It's trivially easy to watch the entire radio frequency range at once and triangulate the location of any transmission. If someone more powerful than you wants to stop you, they can.

Just curious what if the transmitter hops freq around? What is the tech to track these?
It's (scarily) available in the commercial sector[1][2] from space if you have the need to purchase their services.
Suffice to say, military and intelligence agencies are probably a few generations ahead of this and you won't find them commenting on strategic capabilities on HN.

Thanks! Technically, what do you think is the biggest obstacle to achieve military grade hopping? Is it just cost, or something you simply cannot buy from open market AND cannot make one if you have the knowledge?
