The Hotdish and LNB about which you speak is recommended by Mike Kohl as being a good substitute for the standard Shaw dish. If Mike says it will work, you can bet it will work. You should be able to get some signal (above the 18 you are getting) even with the 60e. The 18 is likely due to "noise" in the air and you will see this level no matter where the dish is pointed, and also indicates that your receiver and LNB are conmmunicating and that there is likely no connection problem between the dish and the receiver.
That being said, I believe Frenchphile is right on when he says it's a pointing problem: you must have the correct data for Anik F1R at your Florida location; your mast must be plumb; you must set the correct elevation on your dish and clamp it down before you start to search for the signal by rotating the dish in azimuth; if using a compass to get the azimuth, you must be sure that you're using the magnetic azimuth data; recommend you use dishpointer.com or equivalent instead of a compass; you must be sure there is nothing blocking your line of sight. Be sure, as you rotate your dish in azimuth, that you give the signal meter on the 207 ten to fifteen seconds to react before making the next movement of the dish. If the receiver is not yet authorized, use channel 299's signal meter when searching for the signal. I really don't think your problem lies with your equipment.
With regard to the stacked/nonstacked question, was your 207 previously used with another dish/LNB, and, if so, what kind of dish? Once upon a time I used a single dish, similar to your setup, pointed at Anik F2 only, and I believe my receiver was mapped to "unstacked". I say that because when I put up my 75e quad (unstacked) dish, that same receiver worked with the 75e without changing the V-Code.
