My father regailed tales of his college years where it was a game to have a HAM radio operator start broadcasting and to have teams try to find where they were hiding, first.
More challenging? Not really. It does require multiple boots on the ground to do it.
Multiple boots on Iranian ground is tricky for Americans right now.
This seems to be a common treasure hunt game conducted by HAM clubs.
Presumably doing it locally within a known few mile radius is different from nation-scale broadcast areas bounced from god-knows-where?
