I never got a signal on my meter for G10R but I just gave up and did a blind scan. I got one TP with 4 channels, 2 scrambled. I figured out what they were, peaked elevation and skew then move the dish a tiny bit and did another blind scan. FoundI was going in right direction re-peaked and moved over some more. Scanned and NUTZ-- had White Springs. Went back the other way and got UW! Adjusted skew and rescanned and had them all!----- Squealer Meter still would not respond, but I repeaked and called it a day.... Hm... I think I finally got the reason why people think BlindScan is SO important::: it is because it is!
I've not had luck with those squealer meters either Pop. I guess I just don't have the knack for them either.
I do know one thing. It's really easy to end up too far as you realized. It's wild how much 5 or 6 or even 10 degrees really is. Seems like just a hair movement is a really long way, and I know that it is when magnified to the thousands of miles out in space all those birds are!
