We receive HD channels for free ( over the air ) from Toronto and Buffalo, using this
Channels we pick up
My TV has 2 internal ATSC/NTSC tuners so I've connected my CM4228 (on the roof) to one of my inputs, scanned and picked up the following Buffalo channels:
WGRZ - 2-1 NBC HD 1080i
WIVB - 4-1 CBS HD 1080i
WNLO - 4-3 UPN SD
WKBW - 7-1 ABC HD 720p
WIVB - 23-1 CBS HD 1080i
WNLO - 23-3 UPN SD
WUTV - 29-1 FOX HD 720p
WUTV - 29-2 FOX SD
WUTV - 29-3 FOX SD
WNED - 43-1 PBS HD 1080i (24 x 7 HD)
WNED - 43-2 PBS SD
WNED - 43-3 PBS Bright SD
These come in on a 75 to 80% basis, but are subject to drop-out -- specially WGRZ, and WUTV. The signal levels appear OK approx 85% of the time. (The set only has a bar that shows GOOD - NORMAL & BAD. Most of the time it is between NORMAL & top of BAD. When it goes BAD, it begins to pixellate and drops out.
The Toronto channels all come in at the top of NORMAL to mid-GOOD.
I get:
CBLT - 5-1 HD 1080i
CFTO - 9-1 HD 1080i
CBLFT - 25-1 HD 1080i
CITY - 53-1 HD 1080i
CKXT - 66-1 HD 1080i
I don't like clutter at all, and like to have things hidden out of sight, kind of like a north american thing these days with the whole makeover shows and home designs really. My house is wired for cat 6 and every room in the house has a face plate that has ethernet socket, cable, satellite and audio.
