Hi Dave and gang,

Here is a link to a youtube video from last nights reception of the 610 KHz
AM broadcast station in Canada that was causing RFI on 1.830 KHz.
https://youtu.be/SeL4TcnkWN8

I have now encountered this interference 3 nights this week, always around
10:30 PM EDT (0230 UTC).  I will also try contacting this station to file a
complaint as my recording provides enough evidence that it's indeed CKTB
(recorded the announcers name and their frequency, etc.).  This station is
413 miles from my location.

73,
Don (wd8dsb)
