I just bought a Chaparral Corotor II on eBay - its in the postal system right now. It comes with Star Track C and Ku Lnb, but I have a couple commercial LNBs - 2x Norsat 8520 and a mystery LNB to pick from and a Norsat 6606Afor Ku, though I'd prefer to find a 4106A or something along its specs. The 6606A has 1M stability, which doesn't sound very good. I have no idea if the Star Tracks are any good. I have been running a Titanium CK1S with great success on both C and Ku on my 10ft KTI, getting all but a very few transponders - like AMC 21 12168 H 4444 even though I get all the rest on AMC 21, but this wouldn't be a hobby if I stopped when everything is working well - would it? I'm not entirely sure that the corotor will be any better than my current setup, but it is a hobby after all. I already am running an ASC1, so after I run a shielded wire to run the corotor, I'm good there. Here is a pic of the feed horn and LNBs I took down from a commercial setup recently. 2 are Norsat 8520. I don't know the other. Any idea what brand or model it could be? Any other suggestions for the Ku side?
