FR1 is 107.3 W, not 105. Try looking on Sathint.com to get an idea of what's on what sat, they're usually pretty accurate and the site is easy to navigate. On 107.3 W there should be a bunch of CTV channels, I scan in 32 ITC channels there. On 105W, you should pick up Cozi TV and NBC.
Dishpointer.com is a good site to check all the settings for your dish and azimuth for all the SATs.
I don't have a DJ-1997 receiver, so I can't help there, but there is members on here that do, that'll most likely chime in if you need help with that.
I watch stuff mostly on 97, 99, and 101W. What kind of programming do you like? News, classic shows, etc, etc. Might be able to tell you what sat would have stuff you'd like.
I don't know what brand dish yours is, but I have a mount that looks just like yours on one of my dishes. I had two, but I gave one away.
What are the channels that you are getting? If you can list off some of the channels you are getting, we can tell for sure what sat you're on.
25' high, that is up there!
