Yep Lynn, you are right. I reran the 34w and darn if Calgary can see it very 
very low on the horizon. Looks like it gets a bit better view on the 
northern swing of its inclined orbit which would certainly explain why it 
seems to come up in strength for Jody. So Skynet 4D is in the mix. Guess we 
need a beam heading to see were it is coming from.
