The following channel is the one that I see signal strength, but no image:
WVNY-DT (Digital)
Channel: 13 (22.1)
Network: ABC
Maximum ERP: 10.000 kW

Does this help?

WVNY-DT on channel 13 is very difficult to get in the Montreal area, for several reasons:
- WVNY_DT's signal has a null to the north -- both because it has to protect CKTM in Three Rivers, and because the antenna is located below and south of the summit of Mount Mansfield. It is only throwing about 1kW ERP towards Montreal, not the 10kW which is the maximum it throws (in another direction.)
- depending on where you are located in Montreal, you'll have severe adjacent channel interference from analog CFCF-TV 12 or co-channel interference from CKTM 13 Trois Rivieres.
- low power VHF-Hi is notoriously bad for penetrating small aperture windows, so you would need an outdoor antenna, usually a 10-element yagi, to get it. Check in the digitalhome.ca/forums for the Montreal area to see how other people do it. I don't think I've read of anyone getting WVNY with an indoor antenna in the Montreal area. Most people can't get it with an outdoor antenna, but those that do are using channel-cut yagis, or DBGH with NARODs (see the Antenna R&D section of digitalhome forums for an explanation of NAROD).
It's possible that things will get better in 17 months when 12 and 13 flash-cut to ATSC signals, since their power levels will then be down 15-20 dB.
Compare
WVNY-DT's coverage to
WCAX-DT's or
WPTZ-DT's
The 'green area' (suitable for indoor TV reception) for WCAX extends well onto the island of Montreal, while the green area for WVNY barely crosses the border.
