Not sure if this is just a normal thing that Rogers does every 6 months by changing which QAM channels are available as the last big change was in July when we lost a lot of channels. Of course, this could also be a sign that the end of free QAM channels is near but I resolve to be positive about this. Here's my scan of the channels in Mississauga:
64.xx - 29 music channels. Not going to bother figuring them out because listening to the radio with your LCD TV on just doesn't make sense to me.
83.73 - TV5 (same as 103 on analog cable) 83.74 - PBS Seattle (KCTS) 83.75 - CBC Oshawa (CHEX) 83.76 - CTV Kitchener (CKCO) 83.78 - Teletoon West 83.79 - RDS 83.81 - ABC Seattle (KOMO) 83.82 - CBS Seattle (KIRO)
84.xx - 40 radio stations (same as Daniel's original list?)
113.101 - CityTV Toronto 113.102 - A-Channel 113.103 - CBS Buffalo (WIVB) 113-106 - CBLFT
The PPV/ROD channels I assume are still there on 88.xx, 90.xx, 92.xx and 93.xx but like Monster asked, they do seem to be scrambled more often now than before.
The last two HD sports channels that I was picking up on 72.71 (channel 491) and 94.46 (channel 492) are now scrambled. My brother checked his Rogers box and these channels are no longer available for him either. A shame really as the free HD hockey and basketball were really nice.
