I have a 205 that was previously authorized (not anymore as I upgraded to 505) and I still use that receiver to tweak the dish for F2.
After you upgraded to the 505, you STILL get channels on the 205 that were part of your programming package......?!?! I'm not sure I understand why. Please explain this to me.
I CAN understand that you could still use the 205's signal meter, even if the unit is not authorized.
And, I could understand your receiving 299 (the Shaw Info Channel that is used to download the channel map BEFORE authorization) on the 205 because you have the luxury of having 2 lnb's, but if I understood the OP correctly, he wanted to use only 1 lnb pointed at F2 only, in which case, IMHO (and based on my similar setup), he will not receive. I think this will present a problem, which I described in a previous post.
Perhaps it would be helpful for the OP to read the Star Choice do-it-yourself installation information on Kusat's website....I'm not sure how up-to-date it is, but it does give information about what can be expected from an unauthorized receiver. And, again, this website presumes you are going to get signals from BOTH satellites.
