Update:
Got the following email forwarded by another ham:
This confirms my suspicions about the signal on 1915 kHz. The system
also operates on 3250, 4400 and 5300 kHz.
Northern Radar is the contractor responsible for installing the hardware.
As Mr. Hansen of Northern Radar correctly notes, 1850-2000kHz is a
shared allocation in Canada...amateur, radiolocation and
radionavigation.
If they continue testing it through the weekends of the CQ160M contest
in January and February, I suspect there will be many more complaints.

Hi Doug,
Sorry for the delay getting back to you. I was out of the office
late last week.
Yes, we are involved in the HFSWR installation in Nova Scotia. It is
a Canadian Military Radar so I can't say too much about it. However I
can say that they do have a co-primary (along with the amateur radio
and radio navigation frequency allocations) allocation/licence at that
frequency. Also, in the future they will be rarely using that
frequency band (it is not one of their primary bands). They are just
using it now while they are doing the initial testing. It should quiet
down shortly if it hasn't already.
Hope that helps.
Regards,
Noah

Hello, Mr. Hansen -
I found your name on the Web as an engineering contact at Northern Radar.
I believe your firm is working on a project with Raytheon to install
an HFSWR system in Nova Scotia.
Recently a new signal has appear at 1.9 MHz +/- that is causing
considerable interference to amateur radio operators in the
Northeastern U.S. It appears to be coming from the Maritime area.
Does your system operate at this frequency?
Please feel free to give me a call on the telephone to discuss this.
603-320-6377.
Thank you,
Doug Grant
