lucky if you can locate anything within a mile radius.

It should not be difficult to locate the source so accurately that you
could go to that position and hear the transmitter and locate it
using land-based direction finding.

However, this usually is not very practical. The interference comes
from countries with little amateur activity, and who wants to go there
for a fox-hunt (which you maybe cannot start right away, you have
to wait until the interfering transmitter is active again).

And then, what are you going to do once the source has been located?
The local authorities are probably not that interested in getting it
off the air...
