Although analog television has ended in Canada, there are still a few analog signals to be found there.
We present an updated list of all analog and digital television stations on lowband TV (ch 2 through 6). Channel 4 seems to be a good one to watch for DTV DX. Powers, though, are fairly low.
This list was compiled by Doug Smith, w9wi and updated by William Hepburn through 03/01/2013. If you'd like to see the list, just click here.
Update 4/2/13: One of the few remaining high power analog stations left on the air in Canada, CKND ch2 Minnedosa, MB has filed to switch to DTV and move from ch2 to ch9.
Mexico has significantly modified their DTV transition plan. The Mexican analog drop-dead date is now December 31, 2015. As in Canada, stations in small cities will not be required to convert at all. However, a far larger proportion of Mexican stations are in areas that ARE required to convert.
Mexico is discouraging, but not prohibiting, use of channels 2-6 and 38-51 for DTV use.
(Update 4/10/13)Just as in the U.S. digital transition, the Mexican government is assigning second channels to their analog stations for transitional DTV use. As in the U.S., stations will eventually elect whether to use these new second channels, or their existing analog channels, for permanent DTV operation.
DTV stations in the US and Canada use MPEG-2 compression to encode their video. Mexico will allow MPEG-2 BUT they will also allow use of the more efficient H.264 compression encoder. Some use of H.264 has already been observed in use in Mexico. H.264 is not compatable with most US TV receivers.
Some analogs going dark: XEFB-2 2013, XEFE 2 2013, XEPM 2 2013, XEWO 2 2014, XHI 2 2015, XHRIO 2 2013, XHTAU 2 2015, XHP 3 2014, XET 6 2013.

(Update 5/23/13) Tijuana analog TV shuts down on May 28th. Visit this RTL for a count-down clock plus more info on the Mexican DTV transition.
WTFDA is the only Radio hobby club in North America that caters to the TV and FM DXer, as well as the amateur radio operator who looks for DX on 6 meters. The term "DX" means "distant reception", and those who "DX" look for weak, distant radio and television signals, with an eye to logging as many of these distant signals as possible or obtaining the most distant reception of a given station. TV and FM signals normally only travel 50 to 100 miles out from their transmitters. DXers love to push the reception boundaries of stations by hundreds or thousands of miles by using their skills, better antennas and equipment, and knowing when conditions are ripe for it.
