Default 1Hz click external noise? - HF Radar ?

Yes and I`ve often heard a regular pulse in the USA every time a radar
antenna swept in my direction within line of sight range. Radar was in
the gigahertz band but the disturbed receiver was at a much lower
frequency and of good quality.


There's a municipal airport, KSDL, about 2 miles
from me. Except for a very occasional tree, it's
line of sight.

Would a radar induced noise tend to attenuate
if my receiving antenna (dipole) were off axis
to the radar? Seems to me that it was indeed
stronger when the lobes pointed toward the
airport.
