Thanks.  Best explanation I've heard.  Your location correlates to the
reports I've received that this is being heard in the North East US better
than rest of the US.

Nearly identical system, different intent:

- It is a high-frequency surface-wave radar (HFSWR) system, developed by
Raytheon Canada for the Canadian military. It seems to be a new version of
the SWR503 MK2 HFSWR system. It is intended to detect ships up to 200 miles
from a country's coast (EEZ) to protect against terrorists, smugglers, and
unauthorized fishing vessels as well as locate vessels in distress. The
present system has been detected at 1915, 3250, 4400, and 5300 kHz.

- It is located at Hartlen Point, NS, near Halifax
       (point Google Earth to   44 35 29.47 N   63 26 49.68 W  )

A very minor amount of egg on my face, how could I know the similar type of
system with a nearly identical modulation scheme indeterminate from dozens
of other systems would be looking for something ON the waves instead of the
waves themselves?

Neat trick, use old technology for a new purpose, like FM broadcast and TV
transmissions for tracking stealth aircraft!
