Yes, I know the Canadian stations have low ERPs, typically less than 50 kW, whereas the US stations are like 800 - 1000 kW. There's a separate thread for that. I dont know why that's the case... Are they trying to save electricity? heheh. or discouraging Americans from picking up their signals across the border? Or encouraging their folks to ditch OTA and get cable instead? (heh)

Just a few general comments:
>> The US went through some adjustments after the June 12, 2009 analog shutdown. The ERPs for several stations were increased as they fine tuned their new equipment and tried to improve reception. I suspect there will be some adjustment period for the Canadian broadcasters as well. You might see some ERPs go up as a result.
>> VHF stations will almost always be limited to ERPs below 100 kW. Even 50 kW is considered to be quite powerful for an ATSC (digital) signal in VHF. UHF stations can go over 100 kW, and Canada already has several of them (going up to about 470 kW).
>> Even in the days of analog-only television, I think we saw the same relative difference in Canadian vs. US ERPs. If everyone is simply trying to maintain the same coverage as they had before, then any analog ERP differences would naturally translate into equivalent digital ERP differences.
